What is Hume AI

Hume AI is a voice technology company that builds AI tools able to sense emotion in speech, not just the words being said. Its main product, the Empathic Voice Interface (EVI), listens closely to tone and rhythm, then replies in a voice that matches the mood of the moment.

Alongside EVI, Hume offers Octave, a text-to-speech model that turns written text into natural sounding audio across many languages, and can even clone a voice from a short clip of audio.

The company also builds tools that help other teams test and improve their own voice AI systems, using real human feedback and simulated conversations to catch problems before they reach users.

Developers connect through an API or SDK, while everyday users can try Hume's voice AI directly through its iOS app.
