    Is there some way to to cancel speech synthesis in progress and replace it with synthesis for a new text. Currently it looks like if speech synthesis is in progress all calls to ‘say:withVoice:’ are ignored.

    I’ve looked at FliteController.h and there is no API that exposes this functionality. I am looking for a way to flush the current synthesis queue and start synthesis for new text.




    There is a method interrupTalking in FliteController. However there is a comment in the header file before this method.

    // Handling not doing voice recognition on Flite speech, do not directly call

    It looks like its just calling [AvAudioPlayer stop] and setting it to nil. So it should be safe to call.



    PS: Is there some way to look at the source code of FliteController.m? I just want to look at the implementation to find out what the methods in the header file do. I don’t want to modify anything. For e.g. I want to find out how AVAudioPlayerDelegate is implemented etc.

    You can look at all of the source for OpenEars and modify it for your app. It’s compiled into a framework for your convenience, but it is all shipped with the distribution as source. Here is another discussion of this question that might be helpful to you:
