I have a projet with OpenEars (1.2.4) integrated in it, for speech synthesis only. When I try to replace the SLT voice with one of the demo voices, the app crashes at the first synthesis, with the following message in the debug console: “Error: flite_hts_engine: specify models(trees) for each parameter.”

Did I miss something in the installation document?

Thanks,
Vincent.

Can you show the code you used? It just sounds a bit like the Emma voice (or whichever voice) is not instantiated at the time you are calling it.

thanks for the swift reaction, this is really good.

Here’s a code extract, the crash error occurs on the line where the stEmma (static variable) is initialized.

Thanks,
Vincent

==========

+(void) sayText:(NSString*)text{

if(stFliteController == nil){
stFliteController = [[FliteController alloc]init];
}

if(stEmma == nil){
stEmma = [[Emma alloc]initWithPitch:0.0f speed:0.0f transform:0.0f];
}

if(theQueue == nil){
theQueue = [[NSMutableArray alloc]initWithCapacity:10];
}

if([stFliteController speechInProgress]){
// NSLog(@”AudioSingleton sayText:%@ –> Will queue it”, text);
[theQueue addObject:text];
}
else{
// NSLog(@”AudioSingleton sayText:%@ –> will say it”, text);
[stFliteController sayWithNeatSpeech:text withVoice:stEmma];
}
}

I would just set it up like the tutorial example:

/openears/tutorial

The singleton is there because of the way the app is using sound, not to encapsulate NeatSpeech. And this works with the Slt voice, so I hoped it would be easy to switch to NeatSpeech.

Regarding the queuing, it’s in place because Slt and the previous sound mechanism I used could’t handle it, and the text come in chunks because of the nature of the app.

I did not expect such a difference between OpenEars and NeatSpeech, but I’ll test further, and let you know if I need more support.

Vincent.

But I’m still struggling to integrate it in my application, even in one of the many view controllers I have. Does NeatSpeech assumes, that the objects will be properties of the root view controller, or can it be any VC ?

Thanks,
Vincent

How are you struggling? Are you instantiating the voice and the fliteController in the emma and fliteController lazy instantiation method that is shown in the tutorial and then referencing them with self. as in:

[self.fliteController sayWithNeatSpeech:@”I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone.” withVoice:self.emma];

?

I’m here to help, just let me know what the hangup is and I’m sure we can figure it out.

1. Make sure you’ve imported FliteController+NeatSpeech.h in the VC header after the import of FliteController.h,
2. Create an ivar and property of the voice and of the FliteController in the VC header, synthesize both in the VC implementation, and for each, override their accessor method with the following lazy accessors:

- (Emma *)emma {
	if (emma == nil) {
		emma = [[Emma alloc]initWithPitch:0.0 speed:0.0 transform:0.0];
	}
	return emma;
}

- (FliteController *)fliteController {
	if (fliteController == nil) {
		fliteController = [[FliteController alloc] init];
        
	}
	return fliteController;
}

Then, you don’t initialize either ever, or do any checking of whether they are instantiated, and you don’t have to queue, you just reference them like so:

[self.fliteController sayWithNeatSpeech:@”I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone.” withVoice:self.emma];

Also, just for sanity, double-check that you’ve added the -ObjC other linker flag to the target.
