Build voice and emotion-aware AI workflows with Hume's MIT-licensed TypeScript SDK for hosted speech, expression, and conversational APIs.
Hume AI fits teams building conversational voice experiences that need more than transcription and text replies.
You need a fully offline voice stack.
The SDK can help teams test how expression and speech signals affect user experience.
Your application only needs basic speech-to-text.
Most voice AI systems optimize for transcription or command execution, not how a person sounds or feels. That limits products where tone, expression, timing, and emotional context shape the user experience.
Developers also need client libraries that make these APIs practical to use in real applications. Hume AI's SDK gives teams a typed integration path for adding empathic voice and expression analysis to JavaScript and TypeScript projects.
The SDK gives JavaScript and TypeScript teams a maintained client for interacting with Hume AI services.
Hume's product focus centers on speech, expression, and emotion-aware AI rather than plain text generation alone.
The SDK helps teams add Hume capabilities to apps without hand-writing every API request.
Both platforms help developers add voice generation and conversational audio to applications, but they make different tradeoffs. Hume publishes an MIT-licensed TypeScript SDK and positions its product around emotion, expression, and empathic interaction. ElevenLabs sells a managed proprietary API with published subscription tiers, while its on-prem deployments are custom-priced.
| Feature | Hume AI | ElevenLabs |
|---|---|---|
| SDK license | MIT TypeScript SDK | Proprietary platform |
| Deployment model | Open source client SDK for hosted Hume APIs | Managed API, with custom on-prem deployments |
| Product focus | Emotion-aware voice, expression measurement, empathic interaction | Broad voice generation, dubbing, speech, and agent tooling |
Hume is the better choice when your team wants open source client code, typed SDK ergonomics, and a product designed around emotional expression rather than generic text to speech alone. ElevenLabs is still worth considering when you need its broader managed voice product surface, large voice catalog, or enterprise purchasing path for a proprietary platform.
It is a TypeScript client for using Hume AI APIs from JavaScript and TypeScript applications.
No. The SDK is open source, but it connects to Hume AI services.
Hume AI is best for voice and interaction products where emotion, expression, or tone analysis matters.
