Know what the customer really feels
Today, customer service goes far beyond resolving a request: it's about understanding emotions, frustrations, enthusiasm, or mistrust in real time. Sentiment analysis, powered by artificial intelligence, allows companies to automatically detect the emotional tone of calls and translate that information into strategic decisions.
Technologies like CallCabinet Speech Analytics not only transcribe what was said, but also identify how it was said, giving your team a competitive advantage based on real, emotional data.

What is sentiment analysis in recorded calls?
Sentiment analysis is an advanced feature within voice analytics platforms like CallCabinet, which applies artificial intelligence and natural language processing (NLP) algorithms to interpret a speaker's emotional state during a conversation.
It detects patterns in tone of voice, speed, words used, and context, classifying emotions as positive, neutral, or negative. This technology offers CX supervisors and leaders a tool to understand the customer experience beyond traditional metrics.
Key benefits of sentiment analysis in customer service

Training officers with real-life evidence: Use audio clips that detect emotions to improve empathy in care.
