# kSpeechResetProperty

Set a speech channel back to its default state.

## Declaration

```swift
let kSpeechResetProperty: CFString
```

## Discussion

Discussion You can use this function to, for example, set speech pitch and speech rate to default values. There is no value associated with this property; to reset the channel to its default state, set the string to NULL. This property works with the SetSpeechProperty(_:_:_:) function.
