TranscriptionRequest schema

Field	Type and description
`file` Required	string The audio file to transcribe (multipart file upload). `format: "binary"`
`model`	string Speech recognition model identifier. `default: "openai/whisper-large-v3-turbo"`
`language`	string ISO-639-1 language code to hint the recognizer.
`response_format`	string Format of the transcription response. The route always requests `verbose_json` internally (for accurate billing and segment data), then converts to the client-requested format before returning. Unknown values default to `json`. `text`, `srt`, and `vtt` are returned as `text/plain`; `json` and `verbose_json` are returned as `application/json`. Allowed values: `["json","verbose_json","text","srt","vtt"]` `default: "json"`
