The endpoint accepts common audio container/codecs (e.g. WAV, MP3, WebM/Opus, M4A). Oversized or unsupported uploads are rejected:413— the audio file is too large.415— the audio format isn’t supported.
Exact maximum file size and the full list of accepted formats depend on the
deployment. If you hit
413/415, downsample/convert to 16 kHz mono WAV — the
most broadly supported input — or check the
API Reference. See Errors for
