Speech-to-Text (STT)

Speech-to-Text (STT)

Transcribe audio to text

SpeechToText class

📍 src/core/SpeechToText.ts:54

SpeechToText capability class Provides speech-to-text transcription with model introspection

Example:

typescript
const stt = SpeechToText.create({
  connector: 'openai',
  model: 'whisper-1',
});

const result = await stt.transcribe(audioBuffer);
console.log(result.text);

const detailed = await stt.transcribeWithTimestamps(audioBuffer, 'word');
console.log(detailed.words);
Static Methods

static create()

Create a new SpeechToText instance

typescript
static create(config: SpeechToTextConfig): SpeechToText

Parameters:

  • config: SpeechToTextConfig
