name venice-audio-speech description Generate speech from text via POST /audio/speech, and clone a voice via POST /audio/voices. Covers TTS models (Kokoro, Qwen 3, xAI, Inworld, Chatterbox, Orpheus, ElevenLabs Turbo, MiniMax, Gemini Flash, Gradium), voices per family, cloned-voice handles, output formats (mp3/opus/aac/flac/wav/pcm), streaming, prompt/emotion styling, temperature/top_p, and language hints. Venice TTS ( /audio/speech ) POST /api/v1/audio/speech converts text to an audio stream or file. OpenAI-compatible — the OpenAI SDK's audio.speech.create() works as a drop-in. Use when You want narration, voice replies, or UI audio from text. You need a specific voice family (ElevenLabs, Kokoro, xAI, Qwen 3, Orpheus, Chatterbox, MiniMax, Inworld, Gemini Flash). You want streaming audio returned sentence-by-sentence. You need style/emotion control on supported models. For music generation (lyrics + instrumental), see venice-audio-music . For transcription (audio → text), see venice-audio-transcription . Minimal request curl https://api.venice.ai/api/v1/audio/speech \ -H "Authorization: Bearer $VENICE_API_KEY " \ -H "Content-Type: application/json" \ -d '{ "model": "tts-xai-v1", "voice": "eve", "input": "Hello, welcome to Venice Voice.", "response_format": "mp3", "speed": 1.0, "streaming": false }' --output hello.mp3 Response is the raw audio ( Content-Type matches response_format ). Request schema Field Type Default Notes input string — Required. Up to 4096 characters. model enum tts-kokoro (OpenAPI schema default) See model list below. tts-xai-v1 is the recommended frontier default; pick the model that fits your voice + language needs. voice string, ≤ 512 model-specific (e.g. eve for tts-xai-v1 ) Voice is model-specific — wrong combo = 400 . See voice families. Also accepts a cloned-voice handle ( vv_… ) from POST /audio/voices , paired with the same model that created it. response_format mp3 / opus / aac / flac / wav / pcm mp3 pcm returns 24 kHz signed-16 LE for pipelines. speed number 1.0 Range 0.25–4.0 . streaming bool false true → streamed sentence-by-sentence as audio continues to generate. language string — Optional hint. Accepted form depends on model (Qwen 3 = full names like English ; xAI / ElevenLabs = ISO 639-1 like en ; MiniMax = full names). Unsupported values silently ignored. prompt string, ≤ 500 — Emotion / style cue. Only for models with supportsPromptParam (Qwen 3 currently). Examples: "Very happy." , "Sad and slow." . temperature 0–2 — Sampling temperature. Only for models with supportsTemperatureParam (Qwen 3, Orpheus, Chatterbox HD). top_p 0–1 — Only Qwen 3 currently. Models Model ID Family Highlights tts-xai-v1 xAI Recommended default. Conversational style, ISO 639-1 language hints. tts-kokoro Kokoro OpenAPI schema default. Multilingual, many voices across languages. tts-qwen3-0-6b / tts-qwen3-1-7b Qwen 3 Emotion control via prompt , temperature, top_p. tts-inworld-1-5-max Inworld Character-driven voices (Craig, Ashley, …). tts-chatterbox-hd Chatterbox HD voices (Aurora, Blade, …), temperature. tts-orpheus Orpheus Conversational (tara, leah, jess, leo, …), temperature. tts-elevenlabs-turbo-v2-5 ElevenLabs Turbo Rachel, Aria, Charlotte, Roger, … tts-minimax-speech-02-hd MiniMax WiseWoman, DeepVoiceMan, … Supports persistent voice cloning. tts-gemini-3-1-flash Gemini Flash Star-named voices (Achernar, Achird, Zephyr, …). tts-gradium-v1 Gradium Multilingual across en/de/es/fr/pt, where the voice picks the language (there is no separate language parameter). Proprietary upstream, so capabilities.private is false . Always inspect the entry for your model in GET /models?type=tts — model_spec.voices is the authoritative voice list. Per-model toggles like supportsPromptParam , supportsTemperatureParam , supportsTopPParam live on the internal model definitions but are not currently exposed on /models — treat the request schema below ( instructions , temperature , top_p ) as the support matrix. Voice families (by prefix) Kokoro — lowercase + language/gender prefix: af_* , am_* — American female / male bf_* , bm_* — British female / male zf_* , zm_* — Chinese ff_* , hf_* , hm_* , if_* , im_* , jf_* , jm_* , pf_* , pm_* , ef_* , em_* — French, Hindi, Italian, Japanese, Portuguese, Spanish Examples: af_sky , af_bella , am_adam , bm_george , zf_xiaoxiao Qwen 3 — Vivian , Serena , Ono_Anna , Sohee , Uncle_Fu , Dylan , Eric , Ryan , Aiden xAI — 26 voices.

Portuguese: Alice , Davi Pass a voice that isn't in the chosen model's list and you get 400 . Voice cloning — POST /audio/voices Clone a voice from an audio sample and get back a handle ( vv_… ) you can pass as voice on /audio/speech . multipart/form-data only. curl https://api.venice.ai/api/v1/audio/voices \ -H "Authorization: Bearer $VENICE_API_KEY " \ -F "model=tts-chatterbox-hd" \ -F "file=@sample.wav" Field Notes file The voice sample, multipart field name file . Accepted containers depend on the model. Aim for a clean speech recording of at least 5–10 seconds. model tts-chatterbox-hd (default) or tts-minimax-speech-02-hd . Model Containers Persistence Availability tts-chatterbox-hd MP3, WAV, FLAC, M4A Zero-shot. No voice template is derived; the reference audio is stored with a TTL and re-read on every synthesis call. Handles expire after 7 days , full stop. Regular users. tts-minimax-speech-02-hd MP3, WAV only Persistent. The provider derives a voice template that survives across calls. Auto-deleted after 7 days without use ; each successful TTS request resets the window. Limited access — contact support@venice.ai to have it enabled. A handle is bound to the model that created it. Pass a vv_… handle with a different model on /audio/speech and the call fails. Samples in a container outside the per-model allowlist are rejected with 400 before anything is uploaded. Beyond the shared TTS error codes, this endpoint also returns 403 and 413 (sample too large). Streaming { "model" : "tts-xai-v1" , "voice" : "eve" , "input" : "Hello, this is a long document to narrate. ..." , "streaming" : true , "response_format" : "mp3" } With streaming: true , the HTTP body is a chunked audio stream. Decode as it arrives — useful for latency-sensitive UIs. response_format: pcm pairs well with browser Web Audio API for raw playback.

Errors Code Meaning 400 Bad voice/model combo, input too long (>4096), language hint rejected by a strict model, invalid voice for the chosen model. 401 Auth / Pro-only model. 402 Insufficient balance. 429 Rate limited. 500 / 503 Inference / capacity issue — retry with jitter. Gotchas input hard cap is 4096 chars. For books / long content, split on sentence boundaries and concatenate audio client-side. streaming: true + SDKs: some OpenAI SDK versions don't expose streaming for audio.speech.create ; call the REST endpoint directly and consume the HTTP body. speed compounds with model internal speech rate — extreme values ( 0.25 , 4.0 ) often sound unnatural; keep within 0.8–1.3 for narration. Voice names are case-sensitive ( eve ≠ EVE , af_sky ≠ AF_SKY ). Cloned voices expire. Chatterbox handles die 7 days after creation no matter what; MiniMax handles die after 7 days of no use. Re-clone rather than assuming a handle you stored last month still resolves. Gradium has no language parameter. Pick the voice for the language you want.
