<Badge color="blue">Paid plans only</Badge>

`updateTranscription(options)`

<Badge color="green">{"✓"} Prebuilt</Badge> <Badge color="green">{"✓"} Custom</Badge>

Updates which participants are transcribed for a given transcription instance. If participants are specified or the empty array is passed, any participants that join after this call will not be transcribed unless you call `updateTranscription()` again to include them.

## Parameters

<ParamField body="instanceId" type="string">
  The UUID of the transcription instance to update. Omit to update the default instance.
</ParamField>

<ParamField body="participants" type="string[]" required>
  Session IDs of the participants to transcribe. Pass an empty array to stop transcribing all participants without ending the transcription session. Pass `null` to transcribe all participants.
</ParamField>

## Return value

Returns `void`.

## Examples

```javascript theme={null}
// Transcribe only specific participants
await call.updateTranscription({
  instanceId: '00000000-0000-4000-8000-000000000000',
  participants: [
    'd8a14d03-58ef-4b7c-824a-181779ab535a',
    '435fa323-65a1-4654-b788-069936da87a0',
  ],
});

// Transcribe all participants
await call.updateTranscription({participants: null});
```
