Voice now belongs to agents. Configure one provider, create multiple agents that share it — each with its own voice.

✨ Highlights

🎙️ Per-agent voice selection

  • Provider-aware voice picker in the Agent form: dropdowns of validated catalogs for OpenAI Realtime (10 GA voices), Google Live (30 prebuilt voices), and Deepgram Voice Agent (Aura models) — plus suggestions with custom cloned-voice IDs for xAI Grok. ElevenLabs Agent voices remain managed on the ElevenLabs platform; pipeline TTS voices are unchanged (per-agent pipeline voice is planned).
  • Safe by default. The provider-level voice becomes the Default Voice — every agent without its own voice behaves exactly as before this release. Unrecognized values (including stale text from the old informational field) log a warning and fall back to the provider default — a bad voice value never fails a call.
  • Observable end-to-end. Every call logs the resolved voice and its source (override / agent / provider-default), and Call History shows it per call — e.g. "Voice: marin (from agent)" — so you can always verify what a call actually used.
  • Instant. Agent voice changes apply on the next call — no engine restart.

🧰 Under the hood

  • Single-source voice catalog (src/utils/voice_catalog.py) shared by the engine's validation, the new GET /api/config/providers/meta endpoint, and the Agent form — verified complete against official OpenAI / xAI / Google / Deepgram documentation.
  • Call History gains voice / voice_source (additive, nullable — no migration steps).
  • Optional voice: key on YAML contexts for headless installs, with identical semantics.

⬆️ Upgrading

Standard upgrade — no migration steps, no config changes required. Existing agents have no voice set and keep using their provider's voice.
