Set the callback function to be called when the Speech Synthesis Manager has finished processing speech being generated on the speech channel.

Declaration

let kSpeechTextDoneCallBack: CFString

Discussion

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

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