What is speech analytics?  

Speech analytics is a technology that utilizes artificial intelligence and natural language processing (NLP) to analyze customer conversations from live or recorded audio data. Contact center managers often use speech analytics to identify and understand their top contact drivers by keyword spotting in conversations. Insights gained from speech analytics can also reveal customer sentiment, customer satisfaction level and overall tone.   

Additionally, speech analytics is used for quality monitoring of voice-related operations since it can indicate call quality and agent performance with a fair degree of accuracy.  

Why is speech analytics important?  

Speech analytics is critically important for today’s businesses as it revolutionizes customer service operations in multiple aspects, enabling your organization to function at peak efficiency all the time. It enables contact centers to:  

  • Identify customer preferences, pain points and satisfaction levels and use them to further improve service quality 

  • Mitigate compliance risks by monitoring calls and ensuring adherence to industry regulations and brand guidelines 

  • Monitor agent-customer interactions and help improve agent performance with actionable feedback and training programs 

  • Increase cost efficiency and streamline processes by identifying scope for improvement in operations 

  • Stand out from the competition by delivering consistently satisfying customer service experiences 

Speech analytics vs. voice analytics   

As we’re learning about gathering data-driven insights from spoken language, distinguishing between voice analytics and speech analytics becomes essential. Below is a quick differentiation between the two.  

Aspect 

Speech Analytics 

Voice Analytics 

🔍 What’s being analyzed?  

Content and context of spoken language — including words, phrases and the meaning conveyed 

Physical characteristics of the voice — such as tone, pitch and speech patterns, plus call clarity and noise levels 

📝 Where is it used? 

Customer service improvement, compliance monitoring, trend analysis, quality assurance and sales optimization 

Primarily used for biometric identification, speaker recognition and emotion analysis 

⚙️ What are the data sources used? 

Transcribed or recorded conversations from customer service calls 

Directly obtained from the source for security or authentication purposes, such as in voice biometrics or VoIP 

🎯 What is the business impact? 

Enhancing customer service, compliance adherence and operational efficiency through insights from conversations 

Security and authentication to ensure the identity of the speaker — primarily for access control and fraud prevention 

🧩 Where is it commonly used? 

Customer service across multiple industries, market research 

Security, law enforcement and FinServ for authentication and fraud prevention 

📊 What are the common metrics analyzed? 

Call duration, silence periods, keyword occurrence and sentiment in the context of the conversation

Types of speech analytics 

 There are two primary types of speech analytics based on the timing of audio data analysis. 

1. Real-time speech analytics 

With real-time speech analytics, audio data is analyzed on live voice calls with customers. This allows agents to access actionable insights, trends and metrics in the moment, so they can improve the interaction quality of their current customer conversation. Real-time analytics reveal insights into customer sentiment and tone and even give cues to agents to enhance the customer experience — all while they are on a call. 

Take this conversation, for instance: the agent realizes the caller is agitated and quickly assigns her to an agent who tops the leaderboard to enable quick redressal. All of this happens on the fly as the agent has real-time access to insights such as customer sentiment and agent performance scores.

2. Post-call speech analytics 

Post-call speech analytics provides you with insights into a voice call only after the call has ended. These insights include — but are not limited to — identifying keywords in conversations and building custom text classification models to help build future customer support processes and strategies. 

Here is an example of post-call speech analytics from a call transcript. It yields metrics like average handle time (AHT), overall customer satisfaction and sentiment on the call. Call quality analysts can get their hands on insights at specific timestamps to map trends and keywords.

Benefits of speech analytics  

Contact center managers use speech analytics platforms to identify the reason for each call, the products mentioned and the callers’ mood — helping them to better understand customer needs, wants and expectations. Instead of making decisions based on assumptions (what they think customers are feeling), speech analytics enables you to make decisions based on what customers are actually saying in real time — removing the guesswork.    

Speech analytics platforms gather actionable insights that can be used in the following ways:   

1. Increase customer satisfaction 

The additional layer of AI in speech analytics helps analyze data from customer journey  — including their tone of voice, sentiment and key phrases, so you can:   

  • Better comprehend inscrutable customer behavior and draw insights about satisfaction levels 

  • Detect buyer intent, helping you set up behavioral remarketing campaigns and seamless omnichannel customer experiences 

  • Coach new hires and prep them to address queries faster — helping improve your overall customer experience

2. Improve agent performance and resolution rates  

AI-powered speech analytics software can continuously retrain and improve their analysis models to ensure they provide the freshest insights to your agents — helping them improve performance and resolution rates. Here’s how this is achieved: 

  • Identify repetitive customer queries, help agents automate resolutions and speed up some of their routine tasks to free up time for more complex issues   

  • Empower agents with AI-driven insights about critical performance metrics such as first-contact resolutions and average handle time, meet their SLAs and keep up their productivity level 

  • Help agents identify speech and communication issues during calls and make proactive improvements (for instance, are they talking too fast or facing other speech issues from nervousness?)   

  • Ensure agents stick to their scripts and provide only brand-compliant responses — to avoid any legal/compliance-related issues and establish data privacy

3. Drive operational efficiency

AI-led speech analytics surface business intelligence that can help align your customer service, marketing and sales departments — enabling you to answer questions like:  

  • Are better-priced competitors, poor customer service or misunderstood business value the reasons your customers are not buying your services or products?   

  • Are your sales and customer service teams taking callers through a compliant script?    

  • Is your support team responding promptly and nurturing a positive customer relationship?    

  • What are the skills you should equip your sales and customer service teams with to help them be successful?

Once you are done uncovering the above insights, you can create support strategies to:  

  • Identify process bottlenecks and improve your operational efficiency   

  • Execute on-point capacity planning to keep your agents optimally engaged   

  • Perform root cause analysis of customer issues to identify recurring problems and fix them

  • Monitor mandatory compliance dialogs and phrases, such as settlement disclosures, data breaches and insider trading of sensitive information   

  • Identify employee training opportunities and provide your agents with on-call coaching and assistance

4. Reduce costs

Real-time speech analytics tools and their capabilities also help businesses cut costs in several ways:   

  • Avoid unnecessary callbacks and improve resolution rates 

  • Direct customer queries to cost-effective channels like IVR or online self-service

5. Mitigate risk pertaining to compliances  

Scoring each call and flagging breaches of compliance criteria in real-time can help you stay on the right side of the law and avoid penalties from regulatory authorities. At the same time, call monitoring also helps your compliance team focus on high-risk and low-quality calls. 

How does speech analytics work? 

Speech analytics follows a three-step approach to process, transcribe and analyze unstructured audio data from customers' voice calls.  

1. Data processing  

Speech analytics combines sophisticated artificial intelligence technologies — these include automatic speech recognition (ASR), natural language processing (NLP), machine learning, transcription, tonality-based sentiment analysis and algorithms to process and analyze human speech.  

2. Analysis 

Once the audio data from recorded and live voice calls is processed, speech analytics picks up on customer sentiment — ranging from positive to neutral or negative. For regulatory compliance purposes, it simultaneously masks sensitive information, such as credit card numbers, social security numbers and other personally identifiable information (PII). Keyword spotting can also detect pre-determined words in customer conversations.

3. Generate insights  

The next step is detailed reporting and analysis based on the parameters your team has set — such as call quality, agent performance, sentiment, compliance monitoring and trend identification. Measure these against your customer service KPIs to ensure business goals are being met and to uncover areas of improvement. 

Pro tip: Today, the best speech analytics software can perform automated quality management. It can assess 100% of your conversations, evaluate agent performance based on predefined parameters such as call opening, handoff etc., give individualized improvement suggestions and compare the handling agent’s performance against team benchmarks and industry benchmarks.

Application of speech analytics in different industries 

Even though speech analytics is a comparatively new technology in the market, it is being increasingly adopted by organizations worldwide owing to the level of insights it can bring into contact center operations. Here are some of the real-life use cases of speech analytics software across multiple verticals: 

1. Technology

Speech analytics helps with streamlining customer support and enhancing product development in the technology industry.  

For example, a software company can use speech analytics to:  

  • analyze customer support calls 

  • identify recurring issues and user frustrations 

  • align your product development to address those concerns better.  

 By identifying these pain points, the company can prioritize improvements that directly address customer concerns, leading to a more user-friendly and competitive product. This approach also reduces support costs in addition to improving customer satisfaction, as fewer customers encounter problems due to proactive software enhancements.

2. Financial services

The financial sector employs speech analytics as the primary layer of security enhancement and fraud detection. FinServ brands can identify unusual or suspicious activities by analyzing the voice patterns of callers.   

For example, if a customer's voice pattern during a high-value transaction call differs noticeably from their previous calls, it could be flagged as suspicious. With real-time analysis of voice calls, fraud prevention and security become seamlessly integrated with your day-to-day operations, while legitimate transactions are allowed to proceed seamlessly.

3. Retail industry  

In the retail sector, call center statistics indicate that more than half of customers prefer voice calls to contact support and resolve their issues. Retail companies often gather lots of data through customer interactions — and analyzing these conversations can provide valuable insights.  

 For example, an apparel store can use speech analytics to: 

  • Monitor customer service calls and identify common concerns or preferences with products. 

  • Use this data to optimize their inventory, stocking items that customers usually purchase more 

  • Train their salespeople to address customer needs better — which helps improve sales and customer satisfaction.
