Flux TTS Voices (managed Voice Agent only)
Deepgram Flux TTS is a voice-agent-first model. It is not available on the POST /v1/audio/speech endpoint — it is offered only through the managed Voice Agent (see the Voice Sessions API), selectable with tts_engine: "flux", where synthesis is turn-based, prosody carries across turns, and it is billed inside the per-minute voice rate. It provides 11 English voices; the default is priya, an Indian-accented English voice, and an unrecognized voice falls back to the default.
