Declaration

let kSpeechSyncCallBack: CFString

Discussion

The value associated with this property is CFNumber object whose value is a pointer to an application-defined synchronization callback function, whose syntax is described in SpeechSyncProcPtr. Passing a CFNumber object that contains the value NULL for the value of this property disables the synchronization callback function.

This property works with the SetSpeechProperty(_:_:_:) function.
