My application has multiple view controllers which all have [self.pocketsphinxController startListeningWithLanguageModelAtPath:lmPath dictionaryAtPath:dicPath acousticModelAtPath:[AcousticModel pathToModel:@"AcousticModelEnglish"] languageModelIsJSGF:NO]; in the viewDidLoad method and [self.pocketsphinxController stopListening]; when dismissing the view controller with a button. However, when I enter one view controller, exit, and then go to another view controller it displays the same statements over and over again in the NSLog depending on how many view controllers I have visited. My app works perfectly fine, but I would like to get this fixed.

NSLog (without the date and time, or my personal stuff):

acousticModelPath is 
Pocketsphinx calibration has started.
Pocketsphinx calibration is complete.
Pocketsphinx is now listening.
Pocketsphinx has stopped listening.
acousticModelPath is
Pocketsphinx calibration has started.

etc…

So I don’t know what the problem is and was wondering if you guys could help?

You either have many PocketsphinxControllers in your app (you can only have one) or you have one PocketsphinxController but many instantiated OpenEarsEventsObserver delegates. Either of these will probably be due to your view controllers having an issue that prevents ARC from releasing them.

I have [self.openEarsEventsObserver setDelegate:self]; in the viewDidLoad methods of all of the view controllers and this as well 

- (OpenEarsEventsObserver *)openEarsEventsObserver {
    
	if (openEarsEventsObserver == nil) {
		openEarsEventsObserver = [[OpenEarsEventsObserver alloc] init];
	}
	return openEarsEventsObserver;
}

regarding the openEarsEventsObserver.

This isn’t quite how object declaration and definitions work in Objective-C. From the docs:

Warning
There can only be one PocketsphinxController instance in your app.

That means a single declaration and definition, and a single instance of that declaration/definition. It’s fine (and intended) to have lots of OpenEarsEventsObserver instances, but if you have lots of them instantiated at once you’ll need to do some logical control in order to prevent them all from sending callbacks simultaneously if that isn’t the result you want.

So how does one make them the same instance.

This is a good book for getting started learning Objective-C and Cocoa Touch for iOS development: http://www.bignerdranch.com/we-write/ios-programming.html

This is an good free course if classes are more your thing: https://itunes.apple.com/us/course/developing-ios-7-apps-for/id733644550

Thanks for your assistance Halle.
