What it is
Hume's Empathic Voice Interface (EVI) is a streaming voice API that returns transcription plus emotional prosody scores and generates speech tuned to user affect. Developers integrate EVI over WebSocket with their own logic or use Hume's hosted conversational LLM. EVI competes with OpenAI Realtime by emphasizing emotional context over pure latency.
Watch out for: Emotion claims should be validated for your population; English-led model coverage.
