You can POST to our OpenAI Transcriptions and Translations compatible endpoint.

Create transcription

For a given audio file and model, the endpoint will return the transcription object or a verbose transcription object.

Request body

• file (Required): The audio file object to transcribe. Supported formats are flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, and webm.
• model (Required): ID of the model to use. Only openai/whisper-small for this case. For other models, refer to models/automatic-speech-recognition.
• language (Optional): The language of the input audio. Supplying the input language in ISO-639-1 format can improve accuracy and latency.
• prompt (Optional): An optional text prompt to guide the model's style or continue a previous audio segment. The prompt should match the audio language.
• response_format (Optional): The format of the output. Options include: json (default), text, srt, verbose_json, vtt.
• temperature (Optional): Controls the sampling temperature, between 0 and 1. Higher values like 0.8 will make the output more random, while lower values like 0.2 make it more focused and deterministic. If set to 0, the model will adjust automatically to increase temperature as needed.
• timestamp_granularities[] (Optional): Specifies the timestamp granularity for transcription. Requires response_format to be set to verbose_json. Options: word - generates timestamps for individual words, segment - generates timestamps for segments. Note: There is no additional latency for segment timestamps, but generating word timestamps incurs additional latency.

Response body

The transcription object or a verbose transcription object.

Create translation

For a given audio file and model, the endpoint will return the translated text to English.

Request body

• file (Required): The audio file object to translate. Supported formats are flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, and webm.
• model (Required): ID of the model to use. Only openai/whisper-small for this case. For other models, refer to models/automatic-speech-recognition.
• prompt (Optional): An optional text to guide the model's style or continue a previous audio segment. The prompt should be in English.
• response_format (Optional): The format of the output. Options include: json (default), text, srt, verbose_json, vtt.
• temperature (Optional): The sampling temperature, between 0 and 1. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. If set to 0, the model will use log probability to automatically increase the temperature until certain thresholds are hit.

Response body

The translated text to English.
