Hume AI

Hume AI is an expressive multimodal AI platform and research lab founded by Dr. Alan Cowen. Hume AI's flagship Empathic Voice Interface (EVI) understands not just what words are spoken, but how they are expressed—analyzing vocal prosody, pitch, cadence, and subtle emotional cues to generate empathetic voice interactions.

### Core Architecture & Capabilities - **Empathic Voice Interface (EVI)**: The first conversational voice API with real-time bidirectional audio streaming, emotional prosody understanding, and dynamic tone modulation. - **Octave Expressive Speech**: Next-generation expressive text-to-speech model capable of laughter, whispers, sighs, excitement, and varied pacing. - **Vocal & Facial Expression Models**: Pre-trained machine learning models that classify over 50 distinct dimensional emotional states from audio and video. - **Developer First**: Robust WebSocket APIs, React and Python SDKs, and pre-built UI components for creating responsive voice agents. - **Safety & Ethical Alignment**: Rigorous emotional safety evaluations to prevent manipulative or deceptive behaviors in conversational agents.
