# soTextDoneCallBack

## Declaration

```swift
var soTextDoneCallBack: OSType { get }
```

## Discussion

Discussion Set the callback function to be called whenthe Speech Synthesis Manager has finished processing speech beinggenerated on the speech channel. The speechInfo parameteris a pointer to an application-defined text-done callback function,whose syntax is described in SpeechTextDoneProcPtr. Passing NULL in speechInfo disablesthe text-done callback function. This selector works with the SetSpeechInfo function.
