Welcome,

is there a proper way to destroy the pocketsphinxController?

Does this happen after leaving a view controller and then recreating it? It’s necessary to call [self.pocketsphinxController stopListening] before doing anything that ought to result in the pocketsphinxController being released.

If that isn’t the issue I’d need a bit more information about the structure of your app, any other audio-using operations that are also occurring in the same app, and the complete OpenEarsLogging output (the beginning has been omitted above).

Thanks Halle! That was precisely it. In some cases I was calling stopListening but in others I wasn’t…

Super, glad it’s working for you now!
