JSGF grammar not working

[batilc]

Hello,

I’m trying to test the grammars in OpenEars2.0. However the normal offline JSGF grammar parsing gives an error while initialising. Below resides the partial code and the debugging information.

NSString *languageName = @”page phrases”;
NSDictionary *languageGrammar = @{
ThisWillBeSaidOnce : @[
@{ OneOfTheseCanBeSaidOnce : @[@”HELLO COMPUTER”, @”GREETINGS ROBOT”]},
@{ OneOfTheseWillBeSaidOnce : @[@”DO THE FOLLOWING”, @”INSTRUCTION”]},
@{ OneOfTheseWillBeSaidOnce : @[@”GO”, @”MOVE”]},
@{ThisWillBeSaidOnce : @[
@{ OneOfTheseWillBeSaidOnce : @[@”10″, @”20″,@”30″]},
@{ OneOfTheseWillBeSaidOnce : @[@”LEFT”, @”RIGHT”, @”FORWARD”]}
]},
@{ ThisCanBeSaidOnce : @[@”THANK YOU”]}
]
};

NSError *error = [self.language_model_generator generateGrammarFromDictionary:languageGrammar withFilesNamed:languageName forAcousticModelAtPath:self.acoustic_model];

NSString *lmPath = [self.language_model_generator pathToSuccessfullyGeneratedGrammarWithRequestedName:languageName];

NSString *dictionaryPath = [self.language_model_generator pathToSuccessfullyGeneratedDictionaryWithRequestedName:languageName];

[self.pocket_sphinx_controller setActive:TRUE error:nil];

[self.pocket_sphinx_controller startListeningWithLanguageModelAtPath:lmPath dictionaryAtPath:dictionaryPath acousticModelAtPath:self.acoustic_model languageModelIsJSGF:TRUE];

//This last start listening line gives the error
//By the way, will languageModelIsJSGF be TRUE while using RuleORama?

Pretty sure that issue is that you have a space in your chosen grammar name – it should be named like you would name a constant.

RuleORama should be JSGF:FALSE.

[batilc]

That solved it thank you

[Halle Winkler]

Super!
