Error on Device – Error in render callback

[sethfri]

I brought much of the sample code over to my own app with my own custom vocabulary. This works perfectly on the simulator, but when I try to run the code on a real device, I get the following error repeatedly:

2015-12-21 17:11:22.569 MyApp[823:276842] Error: Error Domain=NSOSStatusErrorDomain Code=-1 “(null)”
2015-12-21 17:11:22.569 MyApp[823:276842] Error in render callback: -1

I have the following code in viewDidLoad:

self.fliteController = [[OEFliteController alloc] init];
self.openEarsEventsObserver = [[OEEventsObserver alloc] init];
self.openEarsEventsObserver.delegate = self;
self.slt = [[Slt alloc] init];
    
 [OELogging startOpenEarsLogging]; // Uncomment me for OELogging, which is verbose logging about internal OpenEars operations such as audio settings. If you have issues, show this logging in the forums.
[OEPocketsphinxController sharedInstance].verbosePocketSphinx = TRUE; // Uncomment this for much more verbose speech recognition engine output. If you have issues, show this logging in the forums.
    
[self.openEarsEventsObserver setDelegate:self]; // Make this class the delegate of OpenEarsObserver so we can get all of the messages about what OpenEars is doing.
    
[[OEPocketsphinxController sharedInstance] setActive:TRUE error:nil]; // Call this before setting any OEPocketsphinxController characteristics
    
// This is the language model we're going to start up with. The only reason I'm making it a class property is that I reuse it a bunch of times in this example,
// but you can pass the string contents directly to OEPocketsphinxController:startListeningWithLanguageModelAtPath:dictionaryAtPath:languageModelIsJSGF:
    
NSArray *firstLanguageArray = @[@"TEST"];
    
OELanguageModelGenerator *languageModelGenerator = [[OELanguageModelGenerator alloc] init];
    
 languageModelGenerator.verboseLanguageModelGenerator = YES; // Uncomment me for verbose language model generator debug output.
    
NSError *error = [languageModelGenerator generateLanguageModelFromArray:firstLanguageArray
                                                             withFilesNamed:@"FirstOpenEarsDynamicLanguageModel"
                                                     forAcousticModelAtPath:[OEAcousticModel
                                                                             pathToModel:@"AcousticModelEnglish"]]; // Change "AcousticModelEnglish" to "AcousticModelSpanish" in order to create a language model for Spanish recognition instead of English.
    
    
if (error) {
    NSLog(@"Dynamic language generator reported error %@", [error description]);
} else {
    NSString *languageModelPath = [languageModelGenerator pathToSuccessfullyGeneratedLanguageModelWithRequestedName:@"FirstOpenEarsDynamicLanguageModel"];
    NSString *languageDictionaryPath = [languageModelGenerator pathToSuccessfullyGeneratedDictionaryWithRequestedName:@"FirstOpenEarsDynamicLanguageModel"];
        
    if(![OEPocketsphinxController sharedInstance].isListening) {
        [[OEPocketsphinxController sharedInstance] startListeningWithLanguageModelAtPath:languageModelPath
                                                                            dictionaryAtPath:languageDictionaryPath
                                                                         acousticModelAtPath:[OEAcousticModel pathToModel:@"AcousticModelEnglish"]
                                                                         languageModelIsJSGF:NO]; // Start speech recognition if we aren't already listening.
    }
}

Hi,

Does your app have mic permission? Otherwise I’ve never heard of an audio render error when using OpenEars (even a permission problem should give some logging info), but you can show your logging results to learn more: Please read before you post – how to troubleshoot and provide logging info here.

You may have already found these, but the tutorial can also be useful for a first integration: https://www.politepix.com/openears/tutorial

and here’s the general FAQ: https://www.politepix.com/openears/support
