# Using Your Custom Voices

> Use your custom voice clones across AI Assistants, Call Control, and the TTS API.

Every voice clone gets a unique voice ID: `{Provider}.{Model}.{voice_id}`

* **Telnyx:** `Telnyx.Qwen3TTS.33226e69-3abd-429b-b64a-86775c9b5850`
* **Minimax:** `Minimax.speech-2.8-turbo.TB4ZMVKanThGeldiw8rLBEg21v4ifjUTRgLpkodJxpMYV`

Find it in the Voice Design Lab by clicking on any saved voice, or build it from the clone response's `provider`, `provider_supported_models`, and `provider_voice_id` fields.

### AI Assistants

Select your custom voice in the assistant's voice settings. Telnyx clones appear under **Telnyx / Qwen3TTS**, Minimax clones under **Minimax**.

### Call Control

Pass the voice ID in the `voice` field of the `speak` command.

### TTS WebSocket

Pass the voice ID as the `voice` query parameter on the WebSocket URL.

See the [TTS streaming guide](/docs/tts-stt/tts-websocket-streaming) for the full connection flow.
