List available voices (deprecated) GET

**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.
