Call sentiment analysis is the process of evaluating the emotional tone of a customer during a phone interaction. It uses AI and speech analytics to detect whether a caller is happy, frustrated, neutral, or angry—providing real-time insights that help improve service quality and customer satisfaction.
What Is Call Sentiment Analysis?
Call sentiment analysis is a key feature of modern speech analytics platforms. It applies natural language processing (NLP) and voice analysis techniques to identify patterns in tone, pitch, word choice, and pacing. This data is used to generate a sentiment score or emotional classification, allowing call centers to monitor customer mood and adjust responses accordingly—either in real time or during post-call review.
