Subject: Can't get speechSynthesizer:didFinishSpeaking: to run on OS X
Date: Tue, 22 Jun 2010 18:26:34 -0500 [thread overview]
Message-ID: <3CB67123-8D98-425F-AAA7-F4C40F6C39A7@gmail.com> (raw)
I would like to add GNUstep/Cocoa speech synthesis to my local copy of emacs. I know this is an GNUstep/OS X only feature and that it will probably never make it into emacs. I also know about emacspeak and such, but I just want something very simple to play around with.
So far I can start and stop speech, but I have been unable to get the didFinishSpeaking callback to work. I have implemented an ObjC class (in nsfns.m) which implements
- (void)speechSynthesizer:(NSSpeechSynthesizer *)sender didFinishSpeaking:(BOOL)success
and I have set an instance as a delegate to an NSSpeechSynthesizer object, but it never fires. If I call it manually as
[[speech_synthesizer delegate] speechSynthesizer: speech_synthesizer didFinishSpeaking: YES];
it works, so I don't think there is a problem with the callback, or the delegate. I read at
http://lists.apple.com/archives/cocoa-dev/2009/Feb/msg00624.html
that asynchronous callbacks rely on the runloop. I think Emacs.app does some weird things with the runloop, so my question is, what must I do to get this to work? Is it even possible? Does Emacs.app even use the runloop? Is it worth the effort? I'm not an expert in either Cocoa/GNUstep or emacs development.
I can send the code if it's helpful, but I thought someone might know offhand what the problem is and and could point me in the right direction to fix it.
Thanks,
Ivan
