transcribe() - RunAnywhere Documentation

const transcription = await RunAnywhere.stt.transcribe(RunAnywhere.audio.wav(bytes))

console.log(transcription.text)

Signature

transcribe(input: AudioInput, options?: SttOptions): Promise<Transcription>

Building an AudioInput

Input constructors hang off the facade as RunAnywhere.audio, so renderer code builds the same values main-process code does:

RunAnywhere.audio.pcm16(bytes, sampleRate?, channels?)
RunAnywhere.audio.float32(samples, sampleRate?, channels?)
RunAnywhere.audio.wav(bytes)
RunAnywhere.audio.file(path)

file is the desktop path: point it at a recording on disk with no reading step of your own.

import { readFile } from 'node:fs/promises'

const transcription = await RunAnywhere.stt.transcribe(RunAnywhere.audio.file(path))

With options

const transcription = await RunAnywhere.stt.transcribe(audio, {
  language: 'en',
  punctuation: true,
  wordTimestamps: true,
})

See STT options.

Checking readiness

const state = await RunAnywhere.stt.state()

Microphone permission

On macOS, recording needs NSMicrophoneUsageDescription in the app’s Info.plist and the user’s consent. Electron surfaces the prompt on first use, and a denial is permanent until the user changes it in System Settings, so handle the refusal rather than retrying.
