Fields
The two defaults are public constants read from the proto defaults, so reference them rather
than a literal:
Language
Leavelanguage unset to auto-detect. Set it when you know the language: detection costs time
and picks wrong on short clips.
Word timestamps
Diarization
diarization = true labels speakers inside the transcription. For a standalone “who spoke
when” answer over a recording, use the diarization namespace:
Translation
translateToEnglish = true returns English regardless of the source language.
