Hume AI

Hume AI specializes in the development of systems capable of interpreting and generating emotionally expressive human communication. Founded by former Google researcher Alan Cowen, the company applies computational work on emotion, such as the semantic space theory of facial and vocal expression, to its technology.

The company's offerings include the Empathic Voice Interface (EVI), a voice-to-voice conversational API that adapts to user tone and emotional signals, and Octave, a text-to-speech model providing control over speaker character and emotional delivery. Additionally, they provide an Expression Measurement API for analyzing emotional signals across audio, video, and text.

In early 2024, the company reportedly raised approximately $50M in Series B funding. Innovation in empathic AI is central to their mission of creating interfaces that can respond dynamically to human emotional states.
