Reply To: followed tutorial, not working for me

[JonLocate]

hey Halle, thanks for your replies. I’ve updated my code a little, to closer match the tutorial. Also I am not sure what you mean by ivars?

the delegate methods are still in my code but i didn’t post them just to make the code shorter. also i turned on verbosePocketSphinx (i think) and the logging output is the same as when only using [OpenEarLogging startOpenEarsLogging].

i doubt it has anything to do with how i imported OpenEars into my project since all the classes and methods are fully visible and showing no errors, but i could be wrong, maybe there is a missing reference to something?

thanks very much!
