mode

Optional. Configures transcription mode. Supported values: VERBATIM, SMART. If unspecified, defaults to VERBATIM transcription. In SMART mode, the model performs disfluency removal (eliminating filler words, repetitions, and false starts), light grammatical cleanup, automatic formatting (paragraphs, bullet points, numbered lists), and minor user edits (inline self-corrections). Timestamps and diarization are incompatible with mode SMART.
