Hi,

for some reason xcode wants to compile the .lm file. I removed it from the compile sources before, because xcode obviously couldn’t compile it.
When printing all files in the directory I was expecting the files in, I immediately knew what went wrong…

Only the .lm is missing. I renamed it to .languagemodel and now the language model gets found and xcode doesn’t detect it as a compilable file.

Thanks for your help.

with a languageModelPath which is nil. If your call to OELanguageModelGenerator did not return an error when you generated this language model, that means the correct path to your language model that you should pass to this method's languageModelPath argument is as follows:

NSString *correctPathToMyLanguageModelFile = [myLanguageModelGenerator pathToSuccessfullyGeneratedLanguageModelWithRequestedName:@"TheNameIChoseForMyVocabulary"];

Feel free to copy and paste this code for your path to your language model, but remember to replace the part that says "TheNameIChoseForMyVocabulary" with the name you actually chose for your language model or you will get this error again (and replace myLanguageModelGenerator with the name of your OELanguageModelGenerator instance). Since this file is required, expect an exception or undocumented behavior shortly.

I just noticed that my log shows

Now using the fallback method to look it up. If this is happening more frequently than you would expect, likely causes can be that you are entering words in another language from the one you are recognizing, or that there are symbols (including numbers) that need to be spelled out or cleaned up, or you are using your own acoustic model and there is an issue with either its phonetic dictionary or it lacks a g2p file.

In the sample app its working fine. I added my class as a delegate of OEEventsObserver and when using the OELanguageModelGenerator it gives me a nice long log(mainly about the sphinx stuff) just like the sample app, but with the custom Models it’s still only that one Message i don’t know if thats on purpose or an error.
