Valence AI

What is Valence AI?

Valence AI is an emotion intelligence platform that detects and classifies emotions from vocal tone during live and recorded customer calls. The Pulse API analyzes voice streams in real time and returns emotion classifications so your team can respond with empathy at the moment it matters most.

How does vocal tone emotion detection work?

Valence analyzes acoustic features of speech including pitch, energy, speech rate, and spectral patterns to classify emotions in real time. Unlike text-based sentiment analysis, which only processes what someone says, Valence processes how they say it. The Pulse API classifies 10 core emotions from voice with 92% accuracy.

What is the Pulse API?

The Pulse API is Valence AI core product. It is a REST API that ingests voice streams from live calls or recorded audio and returns real-time emotion classifications. It works with both human agent calls and AI voice agent conversations. Integration takes a single API call.

Who is Valence AI built for?

Valence serves two primary audiences: enterprise contact center and CX teams who want to coach agents, reduce escalations, and improve CSAT scores; and developers building AI voice agents who need emotional awareness to make their agents sound more natural and human.

How is Valence AI different from text-based sentiment analysis?

Text-based sentiment tools analyze the words a customer uses. Valence analyzes vocal tone, which captures emotional signals before a customer explicitly states how they feel. Valence detects the vocal signal in real time so your team can respond before the conversation escalates.

Can Valence AI integrate with my existing voice stack?

Yes. The Pulse API integrates with most agentic voice setups and CCaaS platforms. You send voice streams to the API and receive emotion classifications back in real time.

What results can I expect from using Valence AI?

Teams using Valence have seen a 15% increase in sales close rates from emotion-driven conversation guidance, measurable reductions in escalation rates, and improved CSAT scores.

Does Valence AI work with AI voice agents?

Yes. Valence adds emotional intelligence to AI voice agents. Most AI agents miss emotional cues entirely. Valence gives AI agents awareness of a callers emotional state so they can adjust tone, pacing, and responses in real time.
