  language: 'en',
  punctuation: true,
  wordTimestamps: true,
  diarization: false,
  translateToEnglish: false,
})

Fields

Field	Type	Default	Meaning
`language`	`string`	none, auto-detect	BCP-47 code such as `'en'`
`punctuation`	`boolean`	proto default	Insert punctuation and casing
`wordTimestamps`	`boolean`	proto default	Per-word timings
`diarization`	`boolean`	`false`	Attribute speech to speakers
`maxSpeakers`	`number`	none	Cap the speaker count
`translateToEnglish`	`boolean`	`false`	Translate rather than transcribe

Language

Leave language unset to auto-detect. Set it when you know the language: detection costs time and picks wrong on short clips, which matters more in a browser where the model is small.

Word timestamps

await RunAnywhere.stt.transcribe(audio, { wordTimestamps: true })

Use these to build captions, or to seek an <audio> element to a spoken word.

Diarization

diarization: true labels speakers inside the transcription. For a standalone “who spoke when” answer:

const result = await RunAnywhere.diarization.diarize(audio)

Translation

translateToEnglish: true returns English regardless of source language.
