{
  audio: '',
  content: '',
}

```

### speakEnd

```javascript theme={null}

### asrData

The recognition of each text segment starts with an asrStart and ends with an asrStop, with one or more asrData (incremental push) in between. You can get speech recognition results in the asrData event for display.

{
  content: '',
}
