The important question is about whether it is found in the root level of your app and whether all of its files are within. You can verify this by going to your Products folder, right-clicking on the built app, choosing “Show In Finder”, and then right-clicking on the .app file and selecting “Show Package Contents”. You should then see all the items at the root level of your app, and the acoustic model bundle should be there. If you look inside it, it should have the same files within as it does in the distribution.
