No problem, the best way to replicate for an accent that is not your own accent is to obtain WAV recordings of speech which should work (i.e. it contains the words in your language model) and run it through – (void) runRecognitionOnWavFileAtPath:(NSString *)wavPath usingLanguageModelAtPath:(NSString *)languageModelPath dictionaryAtPath:(NSString *)dictionaryPath languageModelIsJSGF:(BOOL)languageModelIsJSGF;
This should show very quickly whether the issue is in the language model/dictionary and/or is due to an issue with how the app is being tested.
