OpenAI Whisper can transcribe speech in its original language and translate speech into English, but it is not the best default for every job. OpenAI’s current guide recommends gpt-transcribe for ordinary recorded speech in its original language; use whisper-1 when you need its documented translation workflow, timestamps, or subtitle output. Whisper handles completed audio files, not live streaming.
What OpenAI Whisper does
Whisper is an OpenAI speech-recognition model trained on diverse audio. It supports multilingual speech recognition, language identification, and speech translation. It is one of several models available through the Audio API, rather than the required choice for every transcription task. OpenAI’s speech-to-text guide describes the current model options and workflows.
Transcription or translation: choose by the text you need
| Goal | What the result contains | Documented choice |
|---|---|---|
| Transcribe recorded speech in its original language | Text in the language spoken in the recording | OpenAI recommends starting with gpt-transcribe for ordinary recorded speech. Whisper may suit workflows needing timestamps, subtitles, or translation. OpenAI speech-to-text guide |
| Translate speech in another language | English text translated from the audio | The documented Audio API translation endpoint uses whisper-1 and translates into English only. OpenAI Audio guide |
The translation endpoint is not a general translator that lets you choose any target language. OpenAI states, “This endpoint supports translation into English only.” Translation API reference

Completed recordings
For a finished recording, submit an audio file through the relevant Audio API transcription or translation workflow. The current speech-to-text guide lists mp3, mp4, mpeg, mpga, m4a, wav, and webm for transcription. The translation API reference also lists flac and ogg. Check the endpoint documentation for the accepted formats of the operation you are using; do not assume every format listed for translation is accepted by every transcription model.

Plan around file size and supported formats
OpenAI’s Help Center states that legacy whisper-1 Audio API transcription uploads have a maximum request size of 25 MiB. That limit is specific to the legacy Whisper route; it should not be assumed to apply to every current transcription model, whose validation can differ. Check the documentation for the model and endpoint you plan to use, especially for longer recordings. OpenAI Audio API FAQ
Language coverage does not guarantee equal accuracy
OpenAI’s current speech-to-text guide says Whisper supports 98 languages. That is a coverage statement, not a promise of equivalent results across languages, accents, recording conditions, or vocabulary. OpenAI notes that accuracy varies by language. OpenAI speech-to-text guide
