About

Hume AI offers two flagship products for developers building voice and audio applications: EVI (Empathic Voice Interface), a real-time speech-to-speech model that detects vocal cues such as tone, cadence, and emotional expression and adapts responses accordingly; and Octave, a context-aware text-to-speech engine that generates naturally expressive audio rather than robotic synthesis. Both APIs are designed for integration into customer-facing applications, mental health tools, e-learning platforms, and voice assistants where emotional nuance matters. Octave 2, launched in late 2025, delivered a 50% cost reduction and added multilingual support. The platform includes a free tier with 5 minutes of EVI usage per month, with paid plans scaling from $3 to $500 per month depending on volume.
