Emitted when transcription data is received during a call. Transcription messages are automatically separated from regular infoReceived events.

Callback Parameters
| Parameter | Type | Description |
|---|
transcription | object | The transcription data extracted from the _transcription property of the incoming SIP INFO message. |
| Property | Type | Description |
|---|
originator | string | Indicates the source of the transcription, for example, 'user' or 'bot'. |
messages | { text: string }[] | Array of message objects, each containing a text field. |
Example
client.on('transcription', (transcription) => {
const speaker = transcription.originator === 'user' ? 'User' : 'Bot';
transcription.messages.forEach((message) => {
console.log(`${speaker}: ${message.text}`);
});
});
If an incoming info message contains a _transcription property, it is emitted only as a transcription event — not as an infoReceived event. Transcription Filtering
The SDK automatically separates transcription data from regular info messages. No additional configuration is needed — the filtering is handled automatically:
transcription event: Receives only messages that contain a _transcription property.infoReceived event: Receives all other info messages.
This means you can listen to both events independently without worrying about duplicates.
