I have made a demo of voice recognition with openEars and its working fine. But now i want to integrate it with camera control. For example when user shout START camera will start video recording and stop video recording with STOP.
My first question is it possible with OpenEars??
And if yes can you help me to get start.
Do any one know any such application??

This question is a little too broad for the forum, sorry. Feel free to ask specific questions about your code.

So i try to get it work with UIImagePickerController, but when UIImagePickerController comes in play

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

NSArray *words = [NSArray arrayWithObjects:@”START”, @”STOP”, @”HAVARD”, nil];
NSString *name = @”Mahadev”;
NSError *err = [lmGenerator generateLanguageModelFromArray:words withFilesNamed:name];
NSLog(@”%@”,err);
NSDictionary *languageGeneratorResults = nil;

lmPath = nil;
dicPath = nil;

if([err code] == noErr) {

languageGeneratorResults = [err userInfo];

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

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

upto this coding works fine but

[self.pocketsphinxController startListeningWithLanguageModelAtPath:lmPath dictionaryAtPath:dicPath languageModelIsJSGF:NO];

this method doesn’t trigger, so i do not get

– (void) pocketsphinxDidStartListening {
NSLog(@”Pocketsphinx is now listening.”);
}

working….

If you can help me with this it will be awesome.

I know this is a messy kind of question, so feel free if you need more specifications.

Probably it’s not the case that startListeningWithLanguageModelAtPath: doesn’t trigger but rather that it gets to a certain point in the loop and has trouble. If you turn on verbosePocketSphinx and OpenEarsLogging the output will probably tell you a lot about the reason that startListeningWithLanguageModelAtPath: isn’t getting good results. You can search the log output for the words “error” or “warning” specifically or you can post it here (but please make sure both forms of logging have been turned on first so I can really see everything that is happening).

I don’t think that logging has verbosePocketSphinx enabled. If it does, that means that your app has an issue that is blocking before [self.pocketsphinxController startListeningWithLanguageModelAtPath:lmPath dictionaryAtPath:dicPath languageModelIsJSGF:NO];, not during it, since the logging would show it starting but stopping somewhere, but this logging shows nothing that happens after the language model is generated. I recommended showing the relationship between your picker code and the OpenEars code before — without that or the output with verbosePocketsphinx there’s no way to know what is happening since the code above is the code which works in the sample app.

I m really sorry for my explanation its really bad.

So i have create a viewController and put all the method of OpenEars in viewDidload and add this controller as camera overlay.

Pardon me but i don’t understand your point by “I don’t think that logging has verbosePocketSphinx enabled”, can you explain it more so i can help my self by giving you more info.

No problem, just go to /openears and search the page for “verbosePocketSphinx” and you’ll see the property definition. There is also an example of using it in the sample app view controller if you search for that string.
