Reply To: not sure how to use ChangeLanguageModelToFile

[JonLocate]

After looking through the example i modified my code to have a second language model and its paths

NSString *name = @"commandModel";
    
    NSError *commandModel = [lmGenerator generateRejectingLanguageModelFromArray:commandVocab withFilesNamed:name withOptionalExclusions:nil usingVowelsOnly:FALSE withWeight:nil forAcousticModelAtPath:[AcousticModel pathToModel:@"AcousticModelEnglish"]];
    
    NSDictionary *languageGeneratorResults = nil;
    
    if([commandModel code] == noErr)
    {
        languageGeneratorResults = [commandModel userInfo];
// not sure if i need these file vars as they are not in the tutorial but are in the demo app
        lmFile = [languageGeneratorResults objectForKey:@"LMFile"];
        dicFile = [languageGeneratorResults objectForKey:@"DictionaryFile"];
        lmPath = [languageGeneratorResults objectForKey:@"LMPath"];
        dicPath = [languageGeneratorResults objectForKey:@"DictionaryPath"];
    }
    else
    {
        NSLog(@"Error: %@",[commandModel localizedDescription]);
    }
    
    
    

    
    NSString *name1 = @"BreadModel";
    
    NSError *breadModel = [lmGenerator generateRejectingLanguageModelFromArray:breadVocab withFilesNamed:name1 withOptionalExclusions:nil usingVowelsOnly:FALSE withWeight:nil forAcousticModelAtPath:[AcousticModel pathToModel:@"AcousticModelEnglish"]];
    
    NSDictionary *breadlanguageGeneratorResults = nil;
    
    if([breadModel code] == noErr)
    {
        breadlanguageGeneratorResults = [commandModel userInfo];
        breadlmFile = [breadlanguageGeneratorResults objectForKey:@"LMFile"];
        breaddicFile = [breadlanguageGeneratorResults objectForKey:@"DictionaryFile"];
        breadlmPath = [breadlanguageGeneratorResults objectForKey:@"LMPath"];
        breaddicPath = [breadlanguageGeneratorResults objectForKey:@"DictionaryPath"];
    }
    else
    {
        NSLog(@"Error: %@",[breadModel localizedDescription]);
    }

then when i want to change the model i call this

[pocketsphinxController changeLanguageModelToFile:breadlmPath withDictionary:breaddicPath];

not a lot different from the demo app yet the model doesn’t get changed and the model changed delegate method doesn’t get called. any ideas?

Thanks
