The Value of Speech Analytics for Call Centers

What Is Speech Analytics?

Speech analytics uses technology to analyze conversations. AI, machine learning, and other advanced techniques can rapidly process large amounts of data to provide insights into customer sentiment, call quality, and agent performance. It’s also useful for transcribing, sorting, and categorizing calls, automating time-consuming tasks to free call center representatives up for higher-value tasks.

Types of Conversation Analysis

Speech analytics falls into two basic categories — during the call and after the call.

In-call speech analytics lets managers know, based on an ongoing conversation, whether the time is right to prompt the agent to take a particular action or offer certain products, or if the agent needs some support. The result is a better experience for both agents and customers.

Post-call speech analytics can reveal trends like commonly used phrases, as well as uncover the issues that cause customers to reach out to customer service in the first place. In this way, companies can improve their customer experience, increase satisfaction rates, and even begin to develop new products or services.

Speech Analytics vs. Text Analytics

Speech analytics and text analytics offer similar benefits in terms of extracting insights, but they each operate differently.

Speech analytics processes spoken language from audio recordings, using technologies like natural language processing (NLP) to transcribe and analyze vocal tones, emotions, and speech patterns. It’s crucial in call centers for improving customer service and monitoring compliance.

Text analytics, on the other hand, deals with written content from sources like emails, social media, documents, conversations with chatbots, etc. It focuses on identifying keywords, sentiment, and context within text. Both are used to enhance customer insights and operational efficiency, but speech analytics captures nuances of spoken interactions, while text analytics excels in processing large volumes of written data.

How Does AI Speech Analytics Work?

There are several ways of using AI speech analytics for call centers. AI works by transforming spoken language into useful insights through several advanced processes. One of the primary methods it employs is called Natural Language Processing (NLP). NLP is a branch of artificial intelligence that enables computers to understand, interpret, and respond to human language in a way that is both valuable and meaningful.

Here's a breakdown of how AI speech analytics typically works:

1. Audio Capture

The process starts with recording the spoken conversation. This could be a phone call, a meeting, or any audio input. The call recording provides the data needed to analyze the information.

2. Transcription

Next, the recorded audio is converted into text. This step uses speech recognition technology to accurately transcribe spoken words into written form.

3. Data Extraction and Analysis

Once the audio is transcribed, AI can begin to extract and analyze the data. Different AI tools play a different role in this process, so let’s take a look at some of the most common techniques and how they work:

Natural Language Processing

NLP helps the system understand the context, sentiment (e.g., whether the speaker is happy or frustrated), and meaning of the words. It can identify specific keywords, phrases, and patterns in the conversation, categorize topics, and determine the emotional tone of conversations.

Sentiment Analysis

Beyond just understanding words, AI speech analytics can detect the emotional tone of the speaker. For example, it can determine if a customer is satisfied or angry, which is useful for identifying customer communication pain points and improving customer service. Sentiment analysis tools typically categorize calls into one of three categories:

• Positive (happiness, appreciation, excitement)

• Negative (anger, frustration, sadness)

• Neutral (not displaying strong emotions either way)

Data Visualization and Reporting

Data visualization and reporting tools use AI to help make sense of information and present it in the clearest, most relevant ways. Visualizing the information via charts and graphs, for example, helps identify trends and patterns. Integrations with other data sources then enable you to build comprehensive dashboards and reports that can be shared across the organization. These insights provide actionable feedback and recommendations for businesses, helping you understand your customers and improve workflows, processes and training.

Using Real-Time Call Center Speech Analytics

Real-time speech analytics gives you the information you need as soon as you need it. By analyzing live data, AI tools can provide immediate support to help you deal with a call or query there and then.

Techniques like NLP and sentiment analysis can offer immediate solutions before a call turns sour. For example, if it finds the customer is responding negatively to the call center representative, the agent can get real-time insight to change course, offer alternative solutions, or forward calls to an expert supervisor.

With real-time feedback, agents can understand — in context — how they can strengthen their skills, improve the customer’s experience, and become more effective.

Using Post-Call Speech Analytics

Post-call speech analytics can reveal trends like commonly used phrases, as well as uncover the issues that cause customers to reach out to customer service in the first place. Companies can use call center speech analytics software to improve their customer experience, increase satisfaction rates, and even begin to develop new products or services. Let’s take a look at some speech analytics use cases to find out more.

The Rank Group

The Rank Group, one of the UK's leading gaming and entertainment businesses, leveraged the power of post-call speech analytics by using Vonage’s Conversation Analyzer. Recorded calls were a standard practice for The Rank Group even in its old model, but with Conversation Analyzer, they were able to generate call data and derive actionable insights like never before.

The data from Conversation Analyzer allowed The Rank Group to understand the real-time behavior of its agents on a deeper level. Are they putting customers on hold unnecessarily? Do they allow long silences to pass? Are they having the right discussion about the right topic for the given customer? These are the types of valuable insights that Conversation Analyzer unearthed.

Benefits of Speech Analytics

Now you know what it is and how it works, you may be wondering about the benefits of speech analytics. Let’s look at some key advantages and business outcomes to help you understand what speech analytics for call center or contact center organizations can do.

Increased Customer Satisfaction

Speech analytics can help you consistently deliver customer service that turns first-time callers into loyal advocates. Diving deep into customer interactions lets you uncover recurring issues and customer sentiments, enabling businesses to tackle problems before they escalate. The insights gained make customers feel heard and valued, ultimately boosting satisfaction and loyalty.

Vonage’s 2024 Global Customer Engagement report surveyed 7,078 customers aged 18-74, across 17 global markets. It found that when customers have a positive experience with a business, they’re 56% more likely to give positive feedback, 55% more likely to recommend you to friends and family, and 36% more likely to buy additional products. In other words, keep the customer happy and your business will thrive.

Ensures Compliance

Navigating the maze of legal regulations and internal policies can be daunting, but speech analytics simplifies this task. It can be programmed to automatically scan call content for compliance with laws like HIPAA, flagging any deviations in real-time. This proactive monitoring protects your business from hefty fines and legal troubles, while maintaining high service standards. Consistent adherence to internal policies is guaranteed, enhancing operational efficiency and protecting your brand's reputation.

Better Quality Assurance

Quality assurance is no longer a game of chance with speech analytics in play. Unlike human agents, who can't possibly review every call, AI tools can analyze thousands of interactions swiftly and accurately. They generate comprehensive reports, offering actionable insights to enhance agent performance, improve customer satisfaction, and boost sales. Automating QA empowers businesses to maintain a high standard of service consistently, addressing issues before they affect the customer experience.

Easier Coaching

Helps With Personalization

In today's competitive market, personalization is key to standing out. Speech analytics for call centers empowers agents to deliver tailored experiences by analyzing customer interactions for individual preferences and behaviors. With this information, representatives can make relevant recommendations and address issues more effectively. Personalization not only enhances customer satisfaction but also builds stronger, more loyal customer relationships, setting your business apart from the competition.

Less Post-Call Work for Agents

Free your agents from the burden of post-call administrative tasks. Speech analytics automates call summarization, compliance checks, and data entry, providing detailed call logs that allow agents to focus on what they do best — engaging with customers. By reducing the manual workload, speech analytics increases efficiency, minimizes errors, and boosts agent morale. This streamlined approach ensures that your team remains productive and satisfied, leading to better service overall.

Save Money

Speech analytics is a smart investment for cost-conscious businesses. By automating labor-intensive tasks like quality assurance and compliance monitoring, it reduces the need for extensive manual labor, cutting down on operational costs. Improved efficiency and faster issue resolution translate to lower expenses and higher profitability. Enhanced agent performance and customer satisfaction can also reduce turnover and acquisition costs, making your business more financially robust.

Better Understand Agent Performance

Speech analytics for contact center businesses can provide key metrics such as call duration and adherence to scripts. But sometimes there’s more to consider than numbers — and that’s where sentiment analysis comes in. This element of speech analytics uncovers agent efforts not typically captured by traditional metrics, allowing you to highlight, reward, and learn from top performing agents.
