Authorization

Deprecated — this endpoint returns an empty list and will be removed in a later release; the removal will be announced in the changelog.

It listed the voices of the former local text-to-speech provider, which has been removed from the platform. The voices you can use are set per provider on the assistant, and none of them come from this endpoint:

• VoiceDock voice (beta). Set tts_config.provider: voicedock, model voicedock-1 and voice voicedock.
• ElevenLabs. Any voice from your ElevenLabs voice library, as tts_config.voice_id.
• Inworld, Google and xAI text-to-speech. The voices per provider are listed in the tts_config reference on the Assistants page.
• Realtime models (Gemini Live, Grok Realtime, GPT-Live). Set the voice with llm_config.voice; the voices per provider are listed in the llm_config reference.
