機能
Transcribes pre-recorded audio files to text via the Interactions API.
speech_to_text
Transcribes fully-uploaded audio in a single blocking Interactions API request (audio up to 1 hour; 30 minutes when diarization or word timestamps are enabled).
synchronous
Automatically detects and transcribes 85+ languages, including code-switching; language_codes can pin BCP-47 locales.
multilingual_transcription
timestamp_granularities ["word"] returns start/end offsets per word (caps audio at 30 minutes; incompatible with smart mode).
word_timestamps
diarization_mode "speaker" tags segments for up to 8 speakers (caps audio at 30 minutes; incompatible with smart mode).
diarization
Biases recognition toward up to 1,000 supplied phrases (best results with up to 100).
custom_vocabulary
Optional smart mode removes disfluencies, applies self-corrections and structured formatting/inverse text normalization (default is verbatim).
