iOS：OpenEers不起作用

Question

我正在尝试使用OpenEars语音识别套件，但不能在我的iPhone 3GS上运行。我已经编写了他们的教程提供的所有代码片段，但在讲话时没有任何反应。这是我的代码：

LanguageModelGenerator *lmGenerator = [[LanguageModelGenerator alloc] init];

NSArray *words = [NSArray arrayWithObjects:@"EAT", @"DRINK", @"SLOW", @"GO", nil];
NSString *name = @"NameIWantForMyLanguageModelFiles";
NSError *err = [lmGenerator generateLanguageModelFromArray:words withFilesNamed:name forAcousticModelAtPath:[AcousticModel pathToModel:@"AcousticModelEnglish"]]; // Change "AcousticModelEnglish" to "AcousticModelSpanish" to create a Spanish language model instead of an English one.


NSDictionary *languageGeneratorResults = nil;

NSString *lmPath = nil;
NSString *dicPath = nil;

if([err code] == noErr) {

    languageGeneratorResults = [err userInfo];

    lmPath = [languageGeneratorResults objectForKey:@"LMPath"];
    dicPath = [languageGeneratorResults objectForKey:@"DictionaryPath"];

} else {
    NSLog(@"Error: %@",[err localizedDescription]);
}



[self.openEarsEventsObserver setDelegate:self];

[self.pocketsphinxController startListeningWithLanguageModelAtPath:lmPath dictionaryAtPath:dicPath acousticModelAtPath:[AcousticModel pathToModel:@"AcousticModelEnglish"] languageModelIsJSGF:NO];
