Hume AI

Hume AI develops emotionally intelligent voice AI systems that recognize human emotions from speech, face, and text while generating expressive, context-aware speech responses in real-time.

Founded in 2021 by Alan Cowen, the platform combines affective science, semantic space theory, and multimodal AI to create voice models prioritizing emotional nuance over basic sentiment analysis.

Flagship products include EVI (Empathic Voice Interface) for speech-to-speech conversations with emotional listening and response, Octave for natural and expressive text-to-speech synthesis, and the Expression Measurement API to analyze 48 facial and vocal emotion dimensions.

With ultra-low 45ms latency and support for 11+ languages, Hume AI already serves over 100,000 developers in sectors like customer service (40% cost reduction), healthcare (70% improvement in therapy follow-through), and academic research.
