ElevenLabs models also accept a custom voice ID.

Output formats: Model-dependent. Defaults to mp3 except Gemini TTS (wav); Gemini TTS supports wav and raw 24 kHz pcm and rejects other explicit formats. Other available formats include opus, aac, and flac.

Dialogue: Set model=elevenlabs/eleven-v3:dialogue; provide one <voice>: <text> turn per line.

Music generation: Set model=elevenlabs/music-v2, elevenlabs/music-v2.5, google/lyria-3-clip-preview, google/lyria-3.5, stability-ai/stable-audio-3-medium, or stability-ai/stable-audio-3 to generate music instead of speech. google/lyria-3.5 returns MP3 songs with approximate length described in the prompt and does not accept duration; google/lyria-3-clip-preview returns a fixed 30-second MP3 clip; the ElevenLabs Music models support duration (3-300 seconds) and instrumental mode; the Stable Audio models support seconds (1-380), steps, seed, and negative_prompt. Pass any publicly accessible audio URL as reference_audio to POST /v1/audio/speech.
