Error loading Lookup Dictionary

[Powerkey]

I am trying to utilize OpenEars in an iOS app with Swift. Be forewarned, I am a new iOS programmer and the answer is probably something obvious.

I am getting an error loading the lookup Dictionary. Here is the log…

Welcome,

The log looks a little odd, are you sure nothing has been accidentally removed from it?

[Powerkey]

I spaced the message out to be more readable and changed the name of the app. No other edits. After I posted, I noticed that there are other logging routines that I had not enabled. Should I do that and re-submit the log?

[Powerkey]

Just in case I did accidentally delete something, here is the log as-is…

Feel free to copy and paste this code for your path to your phonetic dictionary, but remember to replace the part that says "TheNameIChoseForMyVocabulary" with the name you actually chose for your grammar or language model or you will get this error again (and replace myLanguageModelGenerator with the name of your OELanguageModelGenerator instance).

[Halle Winkler]

Sure, it couldn’t hurt to see the complete logging with all logging options on. Please leave everything in the log as-is – it’s OK to change the app name only, as long as you do a search-and-replace to change it everywhere in the log so it isn’t confusing.

[Powerkey]

Okay, OELogging and verbosePocketSphinx are enabled…

It looks like the acoustic model isn’t really added to the app target.

[Powerkey]

Well, I have looked it over a bunch of times and re-built the app from the tutorial and I always get the same error.

I checked the AcousticModelEnglish.bundle and it appears to be properly added to the project (well, as fas as I can tell, anyway). I went through the steps in the tutorial again with a brand new project and followed the steps exactly. I checked the built application that is downloaded to the phone and the AcousticModelEnglish.bundel is at the root level of the app bundle. It is also selected as a member of the target in Xcode. The Framework Search paths are updated automatically when it was added to the project.

Any suggestions?

I have included the log from the recent re-built project which is simplified. It looks mostly the same as the previous one, but maybe there is something in it that will help determine what I am doing wrong.

The best bet is to make as brief an example as you can, which replicates the issue and show me the smallest amount of code possible that causes it. Swift isn’t supported here by me yet, but I’m up for taking a look at a non-enormous code example and seeing if anything jumps out at me.

[Powerkey]

As I was copying the code I found the problem.

Apparently,

generateLanguageModelFromArray(words, withFilesNamed: name, forAcousticModelAtPath: "AcousticModelEnglish")

is not the same as

generateLanguageModelFromArray(words, withFilesNamed: name, forAcousticModelAtPath: OEAcousticModel.pathToModel("AcousticModelEnglish"))

(damn noobie)

Thanks for your help.

[Halle Winkler]

I’m happy to hear you found the issue!
