My problem: on VC1 everything works perfect, then I move on to VC2 and here when -(void)fliteDidStartSpeaking{} or -(void)fliteDidFinishSpeaking{} events occur it uses methods from the VC1 not the current VC2.

I tried nil-ing OpenEars object (cannot release in ARC) on VC1 before moving to VC2, app is crashing.

To make it work, I had to turn off ARC and manually release all OpenEars objects on VC1 before moving on to VC2.

Is there a way to make OpenEars use proper methods without turning ARC off?

Here is my VC1.h (that malfunctions with ARC on, to make it work: ARC=off in project build settings and release OpenEars objects in viewWillDisappear and alloc/init in viewWillAppear):

#import <Slt/Slt.h>
#import <OpenEars/FliteController.h>
#import <OpenEars/OpenEarsEventsObserver.h>
@interface VC1: UIViewController<OpenEarsEventsObserverDelegate>{
FliteController *fliteController;
Slt *slt;
OpenEarsEventsObserver *openEarsEventsObserver;
}
@property (strong, nonatomic) FliteController *fliteController;
@property (strong, nonatomic) Slt *slt;
@property (strong, nonatomic) OpenEarsEventsObserver *openEarsEventsObserver;

VC1.m

@synthesize fliteController,slt,openEarsEventsObserver;

-(void)say_it{
[self.fliteController say:someTxt withVoice:self.slt];
}
-(void)stop_talking{
[self.fliteController interruptTalking];
}

-(void)fliteDidStartSpeaking{
//do somthing when started speaking
}
-(void)fliteDidFinishSpeaking{
//do something when finished speaking
}
-(void)navToNextVC{//next view
UIViewController *nextVC= [self.storyboard instantiateViewControllerWithIdentifier:@”VC2″];
[self.navigationController pushViewController:nextVC animated:YES];
}
-(void)viewDidLoad{
fliteController = [[FliteController alloc] init];
slt = [[Slt alloc] init];
openEarsEventsObserver = [[OpenEarsEventsObserver alloc] init];
[openEarsEventsObserver setDelegate:self];
}

VC2.h amd .m is essentially the same, just different methods for fliteDidStart(Finished)Speaking.

Thanks.

Is the issue that only VC1 is getting callbacks, or is it possible that VC1 and VC2 are simultaneously getting callbacks from the same speech but you are reacting to the callback in VC1 first and not getting the info that VC2 is also getting the callback? The expectation is that they would both get a callback from the same speech event if they are both instantiated with OpenEarsEventsObserver delegates.

Second question is about what is being set to nil. Did you set FliteController to nil, FliteController’s OpenEarsEventsObserver, or FliteController’s OpenEarsEventsObserver.delegate?

it is crashing while trying:
[fliteController say:[txtArr objectAtIndex:hlIndx] withVoice:self.slt];
