Add voice, expression, and empathy to your applications with a few lines of code. SDKs for every platform, comprehensive docs, and a community of builders.

Capabilities

Build with Emotional Intelligence

Conversational AI

Build AI agents that engage in natural, emotionally intelligent conversations. Integrate voice and chat experiences that understand context, adapt to user sentiment, and respond with genuine empathy.

“Our vision is to transform the traditional map from a static tool into a living companion that makes you love the journey. For that map to truly come to life, it needs a storyteller’s personality. Hume’s technology provides that critical emotional layer, giving a powerful, empathetic voice to the world’s hidden stories.”

Expressive Text-to-Speech

Turn text into expressive, natural-sounding speech. Control tone, pacing, and emotional delivery to create voice experiences that feel genuinely human.

Voice Conversion

Convert any voice into another while keeping the emotional depth, intonation, and expressiveness. The feeling stays—only the voice changes.
