Yes, I added a few audio session override properties in the last version for experimenting with improving bluetooth under these kinds of conditions. In the OEPocketsphinxController docs check out the new properties disablePreferredSampleRate, disablePreferredBufferSize, and disablePreferredChannelNumber to see if any one of them or a combination helps with your situation. I would recommend confirming that everything is working fine in a non-bluetooth implementation, then trying them one at a time, then trying them in groups of two, then all together, all with several repetitions to avoid fluke results, and document your results and choose the least-intrusive combination that helps (if any do). It is better to override these settings as little as possible.
