OK, can you take a look at the new OpenEars 2.01 out today with a significant VAD behavior fix and see if it improves your issue? When I ran your test case, 2.01 correctly detected the speech that wasn’t simultaneous with the sample app TTS voice speech (a couple of the utterances in the recording occur during TTS speech so they wouldn’t be detected in either case). Let me know if you’re seeing an improvement.
