Think about this for a moment: You’re a company owner trying to keep everyone rowing in the same direction in your company, but you don’t know how. That’s where an all hands meeting steps in to help stay afloat in turbulent waters.

 

This guide will walk you through the all hands meeting meaning, how to run it effectively, and what best practices to use. Moreover, you’ll learn how to utilize an AI meeting assistant to make virtual gatherings productive and engaging and unite employees.

 

Key Takeaways:

  • Also called town halls, all hands meetings are company-wide online or offline gatherings that include employees and managers from all levels.

 

  • A town hall aims to bring company members together to share updates, discuss information and company culture, align goals, celebrate wins, and address concerns or questions all at once.

 

  • An AI meeting assistant designed to eliminate noise, record remote meetings, and automatically transcribe and take notes can make meetings productive, enhance communication and collaboration within companies, and foster a sense of unity.

What Is an All Hands Meeting?

company gathering

 

The name is derived from the phrase “all hands on deck,” a signal calling all ship crew members on deck. Specifically, all hands meetings can be online or in-person and occur monthly, quarterly, or annually, which we’ll discuss below.

 

Importantly, they’re more vital for remote, distributed, or hybrid teams, as they interact face-to-face less often. What’s more, opinions expressed during these strategic symposiums can be game-changers and move things forward.

 

How do all hands meetings differ from typical team meetings? The first ones more effectively keep the entire company on the same page and are great for companywide announcements. The second ones are more valuable for specific project updates.

What Is the Purpose of an All Hands Meeting?

purpose of all hands meetings

All hands meetings aim to get everyone on the same page regarding company goals, initiatives, vision, and strategies. After all, departments, teams, and employees can miss the big picture by getting wrapped up in their specific tasks.

 

But that’s only part of the story. All hands meetings aim to:

 

  • Build unity around business goals and strategies by sharing experiences and discussing roadblocks.

 

  • Reinforces company culture, which can be abstract and hard to grasp. Namely, sharing company values and discussing the behavior of leaders who embody them cultivate a value-driven environment.

 

  • Enable leaders to gather different opinions and ideas to arrive at the best possible conclusion. For example, business advisor Glenn Llopis said, “Your voice can challenge the company’s status quo and cultivate innovation.”

 

  • Allow employees to surface rarely-seen large-scale questions about the company’s operations.

 

  • Enjoy a healthy debate based on different opinions to learn new viewpoints, possibilities, and experiences.

 

 

  • Create a positive and supportive company culture by discussing progress,  recognizing achievements, and celebrating milestones.

 

  • Build transparency and honesty by sharing performance updates, challenges, and plans. 

 

  • Let leaders assess the company’s health and make informed decisions through shared feedback and Q&As.  

 

  • Bring together remote employees, ensuring trust and effective communication without frustration. 

 

  • Help quickly spread critical information and adapt strategies in times of crisis or major change. Thus, leaders can proactively address concerns, outline action plans, and manage the situation.

How Often Should a Company Have All Hands Meetings?

meeting frequency

Companies usually host monthly, biweekly, or weekly all hands meetings. Precisely, quarterly meetings are typical for companies that aren’t fast-paced. Once decided, the meeting organizer should schedule them as recurring meetings on participants’ calendars.

 

Smaller companies can host these gatherings weekly to maintain close communication. And larger companies usually hold all hands monthly, as bringing hundreds or thousands of people together at once is challenging.

 

The good news is that modern conferencing tools help connect large groups more easily. For instance, an AI meeting assistant developed with productivity in mind removes background noise, automates transcriptions during remote meetings, and records them flawlessly.

 

As a result, hosting an all hands meeting online has become effortless and effective, enabling companies to organize them frequently.

 

Overall, the frequency depends on whether the company faces rapid changes, prioritizes transparency, and launches projects frequently. For example, companies must share their yearly plans at the start of the year.

 

Moreover, companies adjust the frequency based on employees’ feedback regarding the effectiveness and impact of these gatherings. So, it’s always good to experiment weekly and monthly to come up with the best solution.

How to Run an All Hands Meeting Effectively?

Leaders are often worried about running meetings effectively so employees can speak up and share ideas without confusion or frustration.

 

So, how can you, as a leader, invite participation and expect proactive responses? Moreover, what if opposing opinions lead to conflict, leaving no space for consensus?

 

For example, I remember a company hosting dry, data-heavy, and disengaging all hands meetings. And when leaders shifted those gatherings to a more interactive format, focusing on storytelling rather than statistics, they witnessed a 30% increase in employee engagement scores.

 

They created segments like “Behind the Scenes,” in which different teams shared insights into their daily work. As a result, the company became more transparent and exciting to all employees.

 

Now, let’s dig deeper to learn to hold all hands meetings effectively.

Prepare for Your Meeting

Step 1: Create Your Meeting Agenda

Consider an agenda like this one that includes:

 

  • Welcome & icebreaker (5-7 mins)
  • Company updates (15 mins)
  • Departmental highlights (20 mins)
  • Special topics (20 mins)
  • Guest speaker or special presentation (10 mins)
  • Q&A session (15 mins)
  • Recognition & awards (10 minutes)
  • Closing & feedback (5 mins).

 

Step 2: Change the Meeting Venues

For instance, choose a large conference room, auditorium, or fun off-site space. However, ensure it comfortably accommodates the entire staff and supports technology for presentations and remote participation.

 

Step 3: Invite All Relevant Attendees

The all hands meeting attendees include:

  • The executive team
  • Chief financial officer (CFO)
  • Chief operating officer (COO) and other C-suite executives
  • Department heads and managers
  • All employees
  • Remote workers.

 

Step 4: Survey the Employees

Send out a survey a week before the meeting to gather questions and topics of interest. Because this helps gather input on topics employees are interested in discussing.

 

Step 5: Go Through a Dry Run

Run a technical rehearsal to avoid hiccups, especially when using new technology or formats.

During the All Hands Meeting

Step 1: Start Strong

Kick off with a compelling story or a valuable company milestone or celebrate accomplishments since the last gathering. This also applies to nonbusiness achievements, such as marriage and milestones. Also, consider starting with a meeting icebreaker.

 

Step 2: Keep the Meeting Moving 

  • Include informative updates
  • Incorporate live polls or real-time feedback
  • Give everyone a chance to ask questions 
  • Ask employees to submit questions or discussion topics in advance
  • Listen to diverse groups of presenters with varying ideas
  • Let each department discuss its news and achievements or project updates
  • Plan five-to-ten-minute small group discussions

 

Step 3: Communicate Clearly

  • Communicate your message through compelling visuals, such as slides and videos, to make your speech memorable.

 

  • Ensure an all hands meeting environment of mutual respect so participants can engage in dialogue without conflicts. Interestingly, American educator Stephen Covey wrote that members should be encouraged to understand one another first and then expect others to understand them.

 

  • Invite an expert or a coach to get a fresh perspective and enhance engagement.

 

Step 4: Ensure Post-Meeting Follow-up

  • Distribute a recap with a video recording, main takeaways, and action items.
  • Solicit feedback for continuous feedback: What worked? What didn’t? 
  • Facilitate post-meeting follow-up using an AI meeting assistant designed to automate transcription and note-taking.

All Hands Meeting Best Practices

All hands meeting best practices offer working standards or guidelines for good outcomes. Let’s get started.

 

1. Timing is Everything: Decide your meeting frequency and create a schedule that respects everyone’s time. And we’ve already discussed the frequency above. What about the best time of day? Well, mid-morning or late afternoon typically sees peak engagement.

 

2. Avoid Mundane Meetings: According to a Harvard Business Review study of over the past 50+ years, meetings are taking longer hours and becoming more frequent. Did you know employees shy away from long and boring meetings? So, maintain a strict agenda, allocate specific times for each segment, and prepare concise presentations.

 

3. Keep It Interactive: People want to avoid sitting through a monologue. How can you turn an all hands meeting into a two-way conversation? Use live polls, Q&A sessions, and even interactive quizzes to keep the energy up. And avoid overshadowing introverts.

 

4. Streamline Your Agenda: An all hands meeting without a clear agenda is like a ship without a rudder going off course. Moreover, prioritize updates that affect the entire company. Additionally, include finance, HR, major project milestones, and strategic pivots.

 

5. Celebrate Achievements: Here’s something you’ll want to remember: recognition fuels motivation. So, take time to shine a spotlight on team and individual accomplishments. Maybe your sales team has surpassed its quarterly targets. And what about the development team’s release of a new feature ahead of schedule?

 

6. Address the Elephants in the Room: Transparency builds trust, prevents misinformation, and keeps everyone on the same page. So, are there rumors about funding or layoffs? Address them head-on.

Final Word

The goal of an all hands meeting is to keep every team member informed, engaged, and aligned with the company’s goals, mission, and culture. When properly executed, these meetings foster a united and motivated workforce.

 

The guide above discusses how to make all hands meetings flexible, effective, and innovative to inspire and unite the entire team. And AI meeting assistants like Krisp can significantly enhance meeting productivity, engagement, and effectiveness.

Customer service is all about quick and clear conversations. Call centers connect businesses with customers, no matter where they are. But here’s the thing: with so many different accents out there, understanding each other can get tricky. That’s why call center accent training is super important. It’s a big topic that’s getting lots of attention and some pretty smart solutions nowadays.

What if staff training isn’t the only solution to navigating through different accents? Imagine a world where technology could effortlessly bridge the gap. This is where advanced software solutions come into play and we’ll discuss it in this article.

Scalability ❌ Limited: More resources needed for more agents. ✅ Easy: Quickly scalable across any team size.
Cognitive Load on Agents ❌ High: Constant focus on speech can detract from service. ✅ Reduced: Agents focus more on service, less on speech.
Privacy and Security ✅ Controlled internally. ✅ Depends on the software’s data policies.
Customer Satisfaction Impact ❌ Gradual: Improvements take time. ✅ Immediate: Enhances clarity and comprehension quickly.

Call Center Accent Training Traditional Methods

Accent training methodologies in call centers are as diverse as the accents themselves. They range from traditional in-person training sessions to innovative digital platforms that use speech recognition and artificial intelligence to tailor training to individual needs. These methods typically include:

 

Method Description

Listening and Repetition Utilizing audio recordings of native speakers to improve understanding and mimicry of target accents.
Role-playing Simulating calls with diverse accents to provide real-world practice in a controlled environment.
Feedback and Coaching Coaching agents and offering personalized feedback on their accent and comprehension skills, often through advanced software that can analyze speech patterns.

 

Problems that Accent Localization Solves at Call Centers

Accent neutralization, or accent reduction, aims to make an agent’s accent more understandable to a wide range of callers without erasing their linguistic identity. This approach addresses several key issues in call centers:

  • Improved Customer Satisfaction: Clearer communication leads to more effective resolutions of customer queries, directly impacting CSAT scores.
  • Reduced Miscommunication: By minimizing accent-related misunderstandings, call centers can operate more efficiently, with fewer calls needing escalation.
  • Enhanced Global Reach: Agents with neutralized accents can communicate more effectively with a global audience, expanding the potential customer base for the business.

In this article, we dive deep into a new disruptive technology called AI Accent Localization, which in real-time translates a speaker’s accent to the listener’s natively understood accent, using AI.

 

Accent refers to the distinctive way in which a group of people pronounce words, influenced by their region, country, or social background. In broad terms, English accents can be categorized into major groups such as British, American, Australian, South African, and Indian among others. 

 

Accents can often be a barrier to communication, affecting the clarity and comprehension of speech. Differences in pronunciation, intonation, and rhythm can lead to misunderstandings. 

 

While the importance of this topic goes beyond call centers, our primary focus is this industry.

Offshore expansion and accented speech in call centers

The call center industry in the United States has experienced substantial growth, with a noticeable surge in the creation of new jobs from 2020-onward, both on-shore and globally.

In 2021, many US based call centers expanded their footprints thanks to the pandemic-fueled adoption of remote work, but growth slowed substantially in 2022. Inflated salaries and limited resources drove call centers to deepen their offshore operations, both in existing and new geographies.

 

There are several strong incentives for businesses to expand call centers operations to off-shore locations, including:

  • Cost savings: Labor costs in offshore locations such as India, the Philippines, and Eastern Europe are up to 70% lower than in the United States.
  • Access to diverse talent pools: Offshoring enables access to a diverse talent pool, often with multilingual capabilities, facilitating a more comprehensive customer support service.
  • 24/7 coverage: Time zone differences allow for 24/7 coverage, enhancing operational continuity.

However, offshore operations come with a cost. One major challenge offshore call centers face is decreased language comprehension. Accents, varying fluency levels, cultural nuances and inherent biases lead to misunderstandings and frustration among customers. 

 

According to Reuters, as many as 65% of customers have cited difficulties in understanding offshore agents due to language-related issues. Over a third of consumers say working with US-based agents is most important to them when contacting an organization.

 

Ways accents create challenges in call centers

While the world celebrates global and diverse workforces at large, research shows that misalignment of native language backgrounds between speakers leads to a lack of comprehension and inefficient communication. 

  • Longer calls: Thick accents contribute to comprehension difficulties, causing higher average handle time (AHT) and also lower first call resolutions (FCR).
    According to ContactBabel’s “2024 US Contact Center Decision Maker’s Guide” the cost of mishearing and repetition per year for a 250-seat contact center exceeds $155,000 per year.
  • Decreased customer satisfaction: Language barriers are among the primary contributors to lower customer satisfaction scores within off-shore call centers. According to ContactBabel, 35% of consumers say working with US-based call center agents is most important to them when contacting an organization.
  • High agent attrition rates: Decreased customer satisfaction and increased escalations create high stress for agents, in turn decreasing agent morale. The result is higher employee turnover rates and short-term disability claims. In 2023, US contact centers saw an average annual agent attrition rate of 31%, according to The US Contact Center Decision Makers’ Guide to Agent Engagement and Empowerment.
  • Increased onboarding costs: The need for specialized training programs to address language and cultural nuances further adds to onboarding costs. 
  • Limited talent pool: Finding individuals who meet the required linguistic criteria within the available talent pool is challenging. The competitive demand for specialized language skills leads to increased recruitment costs. 

How do call centers mitigate accent challenges today?

Training

Accent neutralization training is used as a solution to improve communication clarity in these environments. Call Centers invest in weeks-long accent neutralization training as part of agent onboarding and ongoing improvement. Depending on  geography, duration, and training method, training costs can run $500-$1500 per agent during onboarding. The effectiveness of these training programs can be limited due to the inherent challenges in altering long-established accent habits. So, call centers may find it necessary to temporarily remove agents from their operational roles for further retraining, incurring additional costs in the process.

Limited geography for expansion

Call centers limit their site selection to regions and countries where accents of the available talent pool is considered to be more neutral to the customer’s native language, sacrificing locations that would be more cost-effective.

Enter AI-Powered Accent Localization

Recent advancements in Artificial Intelligence have introduced new accent localization technology. This technology leverages AI to translate source accents to targets accent in real-time, with the click of a button. While the technologies in production don’t support multiple accents in parallel, over time this will be solved as well.

State of the Art AI Accent Localization Demo

 

Below is the evolution of Krisp’s AI Accent Localization technology over the past 2 years.

Version Demo
v0.1 First model
v0.2 A bit more natural sound
v0.3 A bit more natural sound
v0.4 Improved voice
v0.5 Improved intonation transfer

This innovation is revolutionary for call centers as it eliminates the need for difficult and expensive training and increases the talent pool worldwide, providing immediate scalability for offshore operations.

 

It’s also highly convenient for agents and reduces the cognitive load and stress they have today. This translates to decreased short-term disability claims and attrition rates, and overall improved agent experience.

Deploying AI Accent Localization in the call center

There are various ways AI Accent Localization can be integrated into a call center’s tech stack.

 

It can be embedded into a call center’s existing CX software (e.g. CCaaS and UCaaS) or installed as a separate application on the agent’s machine (e.g. Krisp).

 

Currently, there are no CX solutions in market with accent localization capabilities, leaving the latter as the only possible path forward for call centers looking to leverage this technology today.

 

Applications like Krisp have accent localization built in their offerings. 

 

These applications are on-device, meaning they sit locally on the agent’s machine. They support all CX software platforms out of the box since they are installed as a virtual microphone and speaker. 

 

AI runs on an agent’s device so there is no additional load on the network.

 

The deployment and management can be done remotely, and at scale, from the admin dashboard.

 

Challenges of building AI Accent Localization technology

At a fundamental level, speech can be divided into 4 parts: voice, text, prosody and accent.

 

Accents can be divided into 4 parts as well – phoneme, intonation, stress and rhythm.

In order to localize or translate an accent, three of these parts must be changed – phoneme pronunciation, intonation, and stress. Doing this in real-time is an extremely difficult technical problem.

 

While there are numerous technical challenges in building this technology, we will focus on eight majors.

  1. Data Collection
  2. Speech Synthesis
  3. Low Latency
  4. Background Noises and Voices
  5. Acoustic Conditions
  6. Maintaining Correct Intonation
  7. Maintaining Speaker’s Voice
  8. Wrong Pronunciations

Let’s discuss them individually.

1) Data collection

Collecting accented speech data is a tough process. The data must be highly representative of different dialects spoken in the source language. Also, it should cover various voices, age groups, speaking rates, prosody, and emotion variations. For call centers, it is preferable to have natural conversational speech samples with rich vocabulary targeted for the use case.

 

There are two options: buy ready data or record and capture the data in-house. In practice, both can be done in parallel.

 

An ideal dataset would consist of thousands of hours of speech where source accent utterance is mapped to each target accent utterance and aligned with it accurately. 

 

However, getting precise alignment is exceedingly challenging due to variations in the duration of phoneme pronunciations. Nonetheless, improved alignment accuracy contributes to superior results.

2) Speech synthesis

The speech synthesis part of the model, which is sometimes referred to as the vocoder algorithm in research, should produce a high-quality, natural-sounding speech waveform.  It is expected to sound closer to the target accent, have high intelligibility, be low-latency, convey natural emotions and intonation, be robust against noise and background voices, and be compatible with various acoustic environments.

3) Low latency

As studies by the International Telecommunication Union show (G.114 recommendation), speech transmission maintains acceptable quality during real-time communication if the one-way delay is less than approximately 300 ms. Therefore, the latency of the end-to-end accent localization system should be within that range to ensure it does not impact the quality of real-time conversation.

There are two ways to run this technology: locally or in the cloud. While both have theoretical advantages, in practice, more systems with similar characteristics (e.g. AI-powered noise cancellation, voice conversion, etc.) have been successfully deployed locally. This is mostly due to hard requirements around latency and scale.

 

To be able to run locally, the end-to-end neural network must be small and highly optimized, which requires significant engineering resources.

4) Background noise and voices

Having a sophisticated noise cancellation system is crucial for this Voice AI technology. Otherwise, the speech synthesizing model will generate unwanted artifacts.

 

Not only should it eliminate the input background noise but also the input background voices. Any sound that is not the speaker’s voice must be suppressed.

 

This is especially important in call center environments where multiple agents sit in close proximity to each other, serving multiple customers simultaneously over the phone. 

Detecting and filtering out other human voices is a very difficult problem. As of this writing, to our knowledge, there is only one system doing it properly today – Krisp’s AI Noise Cancellation technology.

 

5) Acoustic conditions

Acoustic conditions differ for call center agents. The sheer volume of combinations of device microphones and room setups (accountable for room echo) makes it very difficult to design a robust system against such input variations. 

6) Maintaining the speaker’s intonation

Not transferring the speaker’s intonation in the generated speech will result in a robotic speech that sounds worse than the original. 

 

Krisp addressed this issue by developing an algorithm capturing input speaker’s intonation details in real-time and leveraging this information in the synthesized speech. Solving this challenging problem allowed us to increase the naturalness of the generated speech.  

7) Maintaining the speaker’s voice

It is desirable to maintain the speaker’s vocal characteristics (e.g., formants, timbre) while generating output speech. This is a major challenge and one potential solution is designing the speech synthesis component so that it generates speech conditioned on the input speaker’s voice ‘fingerprint’ – a special vector encoding a unique acoustic representation of an individual’s voice.

8) Wrong pronunciations

Mispronounced words can be difficult to correct in real-time, as the general setup would require separate automatic speech recognition and language modeling blocks, which introduce significant algorithmic delays and fail to meet the low latency criterion.

3 technical approaches to AI Accent Localization

Approach 1: Speech → STT → Speech

One approach to accent localization involves applying Speech-to-Text (STT) to the input speech and subsequently utilizing Text-to-Speech (TTS) algorithms to synthesize the target speech. 

This approach is relatively straightforward and involves common technologies like STT and TTS, making it conceptually simple to implement. 

 

STT and TTS are well-established, with existing solutions and tools readily available. 

 

Integration into the algorithm can leverage these technologies effectively. These represent the strengths of the method, yet it is not without its drawbacks. There are 3 of them:

  • The difficulty of having accent-robust STT with a very low word error rate.
  • The TTS algorithm must possess capabilities to manage emotions, intonation, and speaking rate, which should come from original accented input and produce speech that sounds natural.
  • Algorithmic delay within the STT plus TTS pipeline may fall short of meeting the demands of real-time communication.

Approach 2: Speech → Phoneme → Speech

First, let’s define what a phoneme is. A phoneme is the smallest unit of sound in a language that can distinguish words from each other. It is an abstract concept used in linguistics to understand how language sounds function to encode meaning. Different languages have different sets of phonemes; the number of phonemes in a language can vary widely, from as few as 11 to over 100. Phonemes themselves do not have inherent meaning but work within the system of a language to create meaningful distinctions between words. For example, the English phonemes /p/ and /b/ differentiate the words “pat” and “bat.”

table of English phenomes, mapping source speech to a phonetic representation, then the result to the target speech’s phonetic representation

The objective is to first map the source speech to a phonetic representation, then map the result to the target speech’s phonetic representation (content), and then synthesize the target speech from it.

 

This approach enables the achievement of comparatively smaller delays than Approach 1. However, it faces the challenge of generating natural-sounding speech output, and reliance solely on phoneme information is insufficient for accurately reconstructing the target speech. To address this issue, the model should also extract additional features such as speaking rate, emotions, loudness, and vocal characteristics. These features should then be integrated with the target speech content to synthesize the target speech based on these attributes.

Approach 3: Speech → Speech

Another approach is to create parallel data using deep learning or digital signal processing techniques. This entails generating a native target-accent sounding output for each accented speech input, maintaining consistent emotions, naturalness, and vocal characteristics, and achieving an ideal frame-by-frame alignment with the input data. 

 

If high-quality parallel data are available, the accent localization model can be implemented as a single neural network algorithm trained to directly map input accented speech to target native speech.

 

The biggest challenge of this approach is obtaining high-quality parallel data.The quality of the final model directly depends on the quality of parallel data. 

 

Another drawback is the lack of integrated explicit control over speech characteristics, such as intonation, voice, or loudness. Without this control, the model may fail to accurately learn these important aspects.

How to measure the quality AI Accent Localization output

High-quality output of accent localization technology should:

  1. Be intelligible
  2. Have little or no accentedness (the degree of deviation from the native accent)
  3. Sound natural

 

To evaluate these quality features, we use the following objective metrics: 

  • Word Error Rate (WER)
  • Phoneme Error Rate (PER)
  • Naturalness prediction

Word Error Rate (WER)

WER is a crucial metric used to assess STT systems’ accuracy. It quantifies the word level errors of predicted transcription compared to a reference transcription. 

 

To compute WER we use a high-quality STT system on generated speech from test audios that come with predefined transcripts. 

The evaluation process is the following:

  • The test set is processed through the candidate accent localization (AL) model to obtain the converted speech samples.
  • These converted speech samples are then fed into the STT system to generate the predicted transcriptions.
  • WER is calculated using the predicted and the reference texts.

 

The assumption in this methodology is that a model demonstrating better intelligibility will have a lower WER score.

Phoneme Error Rate (PER)

The AL model may retain some aspects of the original accent in the converted speech, notably in the pronunciation of phonemes. Given that state-of-the-art STT systems are designed to be robust to various accents, they might still achieve low WER scores even when the speech exhibits accented characteristics. 

 

To identify phonetic mistakes, we employ the Phoneme Error Rate (PER) as a more suitable metric than WER. PER is calculated in a manner similar to WER, focusing on phoneme errors in the transcription, rather than word-level errors.

 

For PER calculation, a high-quality phoneme recognition model is used, such as the one available at https://huggingface.co/facebook/wav2vec2-xlsr-53-espeak-cv-ft. The evaluation process is as follows:

  • The test set is processed by the candidate AL model to produce the converted speech samples.
  • These converted speech samples are fed into the phoneme recognition system to obtain the predicted phonetic transcriptions.
  • PER is calculated using predicted and reference phonetic transcriptions.

 

This method addresses the phonetic precision of the AL model to a certain extent.

Naturalness Prediction

To assess the naturalness of generated speech, one common method involves conducting subjective listening tests. In these tests, listeners are asked to rate the speech samples on a 5-point scale, where 1 denotes very robotic speech and 5 denotes highly natural speech. 

 

The average of these ratings, known as the Mean Opinion Score (MOS), serves as the naturalness score for the given sample.

In addition to subjective evaluations, obtaining an objective measure of speech naturalness is also feasible. It is a distinct research direction—predicting the naturalness of generated speech using AI. Models in this domain are developed using large datasets comprised of subjective listening assessments of the naturalness of generated speech (obtained from various speech-generating systems like text-to-speech, voice conversion, etc). 

 

These models are designed to predict the MOS score for a speech sample based on its characteristics. Developing such models is a great challenge and remains an active area of research. Therefore, one should be careful when using these models to predict naturalness. Notable examples include the self-supervised learned MOS predictor and NISQA, which represent significant advances in this field.

 

In addition to objective metrics mentioned above, we conduct subjective listening tests and calculate objective scores using MOS predictors. We also manually examine the quality of these objective assessments. This approach enables a thorough analysis of the naturalness of our AL models, ensuring a well-rounded evaluation of their performance.

In the ever-evolving landscape of customer service, contact centers play a crucial role in delivering exceptional experiences. However, the challenges of background noise, poor audio quality and agent’s accents can all hinder effective communication, leading to frustrated customers and agents alike.  In this blog post, we explore the power of Voice Productivity AI software technology and how it is revolutionizing the contact center industry.

The Distracting Noise Barrier: A Challenge in Contact Centers

Background noise and other voices are an adversary that contact centers have long battled, both for agents in the center and those working at home. Whether it’s the bustling office environment, the cacophony of daily life, or technical issues during remote work, noise can significantly hinder communication. This leads to misunderstandings, repeated conversations, and ultimately, reduced customer satisfaction. The struggle is not only faced by customers trying to reach out but also by agents striving to provide elevated service.

Enter Krisp SDKs: The Game-Changing Solution

Krisp’s Voice Productivity AI software is a groundbreaking solution that is transforming the way contact centers operate by eliminating background noise and voices (other agents, supervisors, even children for agents who work remotely) to exponentially improve voice quality. 

 

Krisp has emerged as a transformative force by offering an AI-powered voice processing solution that provides crystal-clear digital voice communication experiences. The technology employs advanced machine learning algorithms to filter out background noise, remove other voices and ensure that only the speaker’s voice is transmitted. This means that customers and agents can communicate seamlessly, regardless of their surroundings or physical environment. In addition, Krisp removes the background noise bidirectionally, from the customer to the agent as well, so that agents always clearly understand their customer.

 

Krisp SDKs integrate into most CCaaS platforms and are available across platforms, including WASM JS, Win, Mac, Linux, Android and iOS and has optimized its package to minimize its footprint and resource utilization while still delivering market-best voice quality performance. Processings real-time communications with no perceived delay added to calls, Krisp SDKs include support for fullband, wideband and narrowband calls. 

Krisp SDKs include:

  • Noise Cancellation: microphone (outbound/uplink) stream, robust for noise types and SNR levels.
  • Inbound Noise Cancellation: speaker (inbound/downlink): optimized for inbound PTSN/mobile, removes background noise from customer to agent and has intelligence to allow ringtones to pass through to the agent.
  • Background Voice Cancellation: removes competing voices around the agent, including other agents and supervisors. There is no need for training or enrolling the agent’s voice. 
  • Accent Localization: localizes Indian English accents so that US-based customers hear US-neutral accents. This is done so that there is no perceived delay during the call and agents sound natural in their speech, tones and pitch. Additional geographic accents will be added.

How Krisp’s Voice Productivity AI Works

Krisp’s technology works on a simple yet ingenious principle. It employs two-way voice processing – one deployed in the microphone stream (uplink/outbound) and one in the speaker stream (downlink/inbound). For the agent, the technology uses AI to distinguish between the agent’s voice and background noise and other voices. All noise and competing voices are then canceled out, leaving only the agent’s voice to be transmitted. For the customer’s inbound audio stream, the technology similarly filters out any residual noise, ensuring that the audio received is crisp and clear. 

 

Krisp SDKs are all integrated on-device with no cloud/server connectivity, processing or storage.

Benefits for Customers

For customers interacting with contact centers, the advantages of Krisp are quantitative and qualitative. First and foremost, the elimination of background noise means that queries and concerns are heard accurately, resulting in quicker issue resolution. This leads to higher customer satisfaction rates and an overall positive perception of the brand’s commitment to quality service. Additionally, improved audio quality reduces the likelihood of miscommunications, misunderstandings, and repetitive conversations. This enhances the overall customer experience and reducing the time required on a call. Krisp contact center customers report on average a 10% reduction in average handle time (AHT), an 8% increase in customer satisfaction scores (CSAT), and a 25% increase in agent satisfaction.

Empowering Contact Center Agents with Voice AI

While the customer experience is paramount, Krisp’s Voice AI technology also greatly benefits contact center agents. Agents are better able to focus on the conversation at hand without struggling to decipher muffled speech or loud distractions. This heightened focus not only boosts their efficiency but also reduces stress levels, leading to improved job satisfaction. With clearer audio, agents can provide more accurate responses, leading to faster call resolutions and increased agent productivity. Agents are able to have clear voice communications independent of their headset type or quality level. In fact, many contact centers using Krisp have reduced their investments and now purchase much lower priced headsets, as Krisp far outperforms and out-delivers even the most expensive headsets.

Bridging the Accent Gap – Accent Localization 🆕

Krisp has developed Accent Localization technology to enable clear communications across countries, languages and accents. Starting with India-based agents for North American customers, agent accents are localized to sound similar to North American accents, lessening the friction between consumers and agents equipped to help them solve their problems. Krisp will be adding additional accent coverage in 2024 for most major markets. This highly valuable breakthrough technology will enable highly qualified agents in emerging markets to be able to serve demanding customers comfortably without the risk of unintelligibility or bias from customers due to accent.

Elevating Work from Home

The global shift toward remote work has posed new challenges for contact centers. Agents are now working from a variety of locations, each with its own set of background noises. Krisp has risen to this challenge by offering a powerful solution that ensures remote agents can maintain the same level of professionalism as their office counterparts. Customers never know if any agent is working in a large, loud contact center, or at home with unpredictable background noises.

Integration and Accessibility

One of the remarkable features of Krisp’s Voice AI technology is its ease of integration into existing contact center platforms. This means that contact centers can seamlessly incorporate Krisp’s voice processing capabilities into their operations without disrupting their existing workflows. Krisp integrates with browser-based applications, as well as native applications, both on desktop and mobile. This approach ensures that the power of Krisp is accessible to businesses of all sizes, from enterprise-level platforms to those serving mid-market and SMB.

The Future of Customer-Centric Communication

In a world where customer expectations are continually on the rise, Krisp is leading the way in revolutionizing how contact centers provide clear voice communications. By addressing the perennial challenge of background noise, audio quality and accents, Krisp’s Voice Productivity AI is enhancing customer experiences, boosting agent productivity, and redefining the parameters of efficient communication.

In conclusion, the power of Krisp’s Voice Productivity AI software within contact center platforms is undeniable. It is reshaping the industry by transforming the way customer interactions occur. The technology’s ability to eliminate background noise, block competing voices, localize accents and deliver crystal-clear audio profoundly impacts both customer satisfaction and agent efficiency. As we move forward in this digital age, Krisp plays a pivotal role in shaping the future of customer-centric communication. Contact center platforms embracing this technology will gain a competitive edge, setting new standards in the realm of customer service.
