# soSpeechDoneCallBack

## Declaration

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

## Discussion

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