# availableVoicesDidChangeNotification

A notification that indicates a change in available voices for speech synthesis.

```
class let availableVoicesDidChangeNotification: NSNotification.Name
```

## Discussion

The system posts this notification when available voices for speech synthesis on the system change. For example, a new personal voice becomes available and the user authorized the app to access personal voices. Or new 3rd party voices become available through an app the user downloads.
