Sentiment Analysis

Gain clear insight into customer attitudes with sentiment analysis

CallMiner’s Eureka conversation analytics platform captures customer interactions and analyzes sentiment across all channels.

Driving business performance starts with understanding your customers

The decisions of customers are driven by sentiment. From attitudes about a brand to opinions of products or services, sentiment plays an outsized role in customer churn, loyalty, and satisfaction. Savvy companies capture sentiment analysis to identify their customers’ positive, neutral, or negative leanings and use that data to better understand customers’ opinions, address their needs, and deliver exceptional experiences.

Analyzing sentiment is an incredibly complex endeavor and choosing the right tools is critical. Survey-based solutions will deliver insight into only a small fraction of your audience. Technology that mines contact center conversations offers a more comprehensive approach – but it requires best-of-breed, automated tools to ensure accuracy, ease-of-use, and cost efficiency.

CallMiner offers a leading sentiment analysis solution in its Eureka conversation analytics platform. By measuring the acoustics in a speaker’s voice and evaluating the overall content and context of a conversation, Eureka enables you determine the true meaning behind spoken words and gain deeper insight into your customers’ sentiment.

The 12 Customer Emotions Brands Must Understand

Frequently asked questions.

Sentiment analysis is a form of speech analytics that monitors conversations and evaluates language and voice inflection to quantify the attitudes and opinions of an individual speaker. Companies use sentiment analysis to evaluate how customers feel about the business, a product or service, or a specific topic.


After identifying the words used in a conversation and evaluating the inflection of a speaker’s voice, sentiment analysis uses an algorithm to score the interaction and quantify the speaker’s positive, neutral, or negative attitudes or opinions. A sentiment score may be based on the rate of speech, the amount of stress or frustration in a customer’s voice, and changes in stress levels indicated by the person’s speech.


Sentiment analytics can help brands better understand their reputation among customers and take action to improve it. Sentiment analysis can also reveal customer attitudes toward specific products, services, and campaigns. By providing real-time insight and prompts for agents based on the sentiment customers are expressing, sentiment analytics can help agents to take the right steps to positively resolve difficult conversations and minimize customer churn.

We saw opportunities right out of the gate. CallMiner helped us visualize the impact of COVID-19 on our call drivers, allowing us to make changes to our IVR system so that customers could leave a voicemail to cancel trips. While other companies had hold times during the initial outbreak from five to 10 hours, we were able to reduce hold times to about seven minutes. Much of this success was due to the insights gleaned from CallMiner.
