# soSpeechDoneCallBack

## Declaration

```occ
soSpeechDoneCallBack = 'sdcb'
```

## 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](../speechdoneprocptr.md).Passing `NULL` in `speechInfo` disablesthe speech-done callback function.

This selector works with the `SetSpeechInfo` function.
