# JavaScript SDK — WebSockets

> Connect to Stream and Transcribe APIs

## Streams

```typescript theme={"system"}
const stream = await client.streams.open({
  sessionId,
  audio: { sampleRate: 16000, encoding: 'pcm_s16le' },
  features: ['transcript', 'soap', 'codes', 'span_anchors'],
});

stream.on('transcript.final', (e) => {});
stream.on('note.section.update', (e) => {});
stream.on('code.suggestion', (e) => {});

const mic = await navigator.mediaDevices.getUserMedia({ audio: true });
stream.streamAudio(mic);

```

## Transcribe (stateless dictation)

```typescript theme={"system"}
const ws = await client.transcribe.connect({
  language: 'en-US',
  punctuation: 'smart',
});

ws.on('interim', (e) => {});
ws.on('final', (e) => {});
ws.on('command', (e) => {});

ws.streamAudio(mic);

```

## Therapy (multimodal)

```typescript theme={"system"}
const ws = await client.therapy.connect({ sessionId });

ws.on('rdoc.activation', (e) => {});
ws.streamAudio(audioStream);
ws.streamVideo(videoEl, { fps: 15 });

```
