Transcription
Transcribe an audio file
Send an audio file and receive the transcript in the same HTTP request/response cycle — no webhooks or polling required. Optionally, the endpoint can also label who spoke when (diarisation) and detect music such as hold tones.
Supported audio formats: WAV, MP3, FLAC, AAC, OGG, MP4, AIFF, OPUS.
Processing may take up to 2min30s, or fail altogether, on long, low-quality, or complex audio. Keep clips short where you can.
