Audio

No model serves this yet

Nothing in the model catalogue supports this route right now. The page stays for reference.
POST/v1/audio/speech
POST/v1/audio/transcriptions
POST/v1/audio/translations

Speech both ways: /v1/audio/speech synthesizes text into audio bytes; /v1/audio/transcriptions turns audio into text (Whisper-compatible); /v1/audio/translations transcribes straight into English.

#Request parameters

  • modelstringrequired

    tts-1 class for speech; whisper-1 class for transcription.

  • inputstringrequired

    speech only: the text to speak.

  • voicestringrequired

    speech only: voice name (alloy, nova, …); available voices per model card.

  • filefile (multipart)required

    transcriptions only: the audio file (mp3, wav, m4a, webm …).

  • languagestringoptional

    transcriptions only: ISO-639-1 hint that improves accuracy.

  • response_formatstringoptional

    speech: mp3 | wav | opus …; transcriptions: json | text | srt | verbose_json.

  • speednumberoptional

    speech only: 0.25–4.0 playback speed.

Two different content types

speech takes a JSON body and returns raw audio bytes; transcriptions/translations take multipart/form-data and return JSON. Don’t mix the two.
