The Finesse SDKs for Python and TypeScript / JavaScript are coming soon. They’ll install from PyPI and npm, and this page will have the guides when they’re out.
They will cover voices, cloning, one-shot and streamed speech, and realtime sessions for voice agents, with retries, timeouts and errors handled for you.

​
Until then, use the API

Everything the SDKs will do works today over plain HTTP and WebSocket, from any language.

Quickstart

From an API key to a WAV file with curl.

OpenAI-compatible endpoint

Use the OpenAI Python or Node SDK with Finesse today.

Clone a voice

From a reference clip to a ready voice.

Realtime WebSocket

Voice agents over one WebSocket.
