Paramètres

input body · string · obligatoire

The text to synthesize. No character cap is published; probe 2026-09-05 saw 5,000 characters succeed and 20,000 return 400 backend_error.

model body · string · obligatoire

Model name to route to; may be an alias, and is rejected if blank.

cache_salt body · string | null · facultatif

Prefix-cache isolation key, overwritten when ref_audio is present. Documented on https://sprag.ai/docs/tts/api.md but ABSENT from Sprag's own published SpeechRequest schema; it is accepted only because additionalProperties is true. Unprobed.

instructions body · string | null · facultatif

Optional voice/style guidance on a preset model; the voice description itself on chorus-design. Probe 2026-09-05 measured an effect on duration but not a directional one.

language body · string | null · facultatif

ISO-639 / BCP-47 tag for the input text; omit to have the model detect it. Chorus serves ten: en, zh, ja, ko, es, pt, ru, de, fr, it.

ref_audio body · string | null · facultatif

Inline data: URL of reference audio for voice cloning. A web URL and a data: URL without ;base64 are both 400. Belongs to the cloning model, not to chorus-voices.

ref_text body · string | null · facultatif

Exact transcript of the reference audio, for voice cloning.

response_format body · string | null · facultatif

Omit and the model's own container comes back. Omit it on a STREAMED request and you get wav.

5 valeurs d’énumération

Valeurs

mp3opusflacwavpcm

speed body · number | null · facultatif

Playback speed multiplier; scales generated duration by roughly 1/speed. Sprag's published schema declares only exclusiveMinimum 0, but probe 2026-09-05 shows 0.2 and 5.0 rejected with backend_error while 0.25-4.0 succeed, so the documented range is enforced by the model backend rather than by request validation.

min 0.25max 4

stream_format body · string | null · facultatif

`audio` streams raw chunked audio; `sse` emits speech.audio.delta / speech.audio.done events; omit for one buffered response.

3 valeurs d’énumération

Valeurs

sseaudio

voice body · string | null · facultatif

Preset speaker id. Ids are lowercase and match case-insensitively; an unknown id returns 400 with the model's valid ids in the message. On `chorus-voices` the nine are aiden, dylan, eric, ono_anna, ryan, serena, sohee, uncle_fu and vivian.

Fonctionnalités

Text to speech

Generates spoken audio from text through an OpenAI /v1/audio/speech shape, returning audio bytes rather than JSON.

text_to_speech

Streaming

Streams raw chunked audio (stream_format=audio) or base64 audio deltas over SSE (stream_format=sse), for pcm and wav output only.

streaming

Output formats

Serves mp3, flac, wav and pcm at 24 kHz mono and opus at 48 kHz mono.

output_formats

Speaking rate control

`speed` multiplies the speaking rate over the documented 0.25-4.0 range.

speed_control

Voice cloning

Clones a speaker from reference audio passed inline as ref_audio and ref_text or saved once as an organization voice.

voice_cloning

Voice design

Creates a voice from a written description through /v1/audio/voices/design previews saved as organization voices.
