Yes it is surely because Open Ears didn’t find the language model files. In my case, I have all the files needed by Open Ears in my bin folder from where I export my IPA. I’m am using the command line for the export so I don’t really know how it works with Flash but you have to include each file (language model, dictionaries, noise dictionary etc…)
Also, when debugging on your device, you can open the Organizer in Xcode, there you’ll find the console that will show everything logged from your Open Ears extension. It really helps debugging the extension.
Tell me if you got it working!
