What it is
Hume AI's Empathic Voice Interface (EVI) is a voice-AI model that combines speech recognition, language generation, and prosodic-tone analysis into a single model. The product reads the emotional tone of the speaker — frustration, hesitation, enthusiasm — and lets the agent adjust its response. EVI is positioned for use cases where tone matters: mental-health support, coaching, and consumer voice assistants. Hume AI is run by former Google DeepMind researcher Alan Cowen and has raised over $50M from EQT Ventures, Union Square Ventures, and Comcast Ventures.
Watch out for: Emotion-AI scoring is heuristic and contested; not appropriate for high-stakes decisions about people.
