Reply To: [Resolved] Clarifications on the improved background noise cancellation feature

Hi Halle,

I’m actually using the VoiceChat mode almost exclusively since the app can also stream IP Camera video/audio. That seems to work as it did before.

I tried adjusting the kVAD_PRESPEECH value from 10 to 20, 50, 100 and it seems to really only change the time it takes to recognize speech. I didn’t notice anything different with the noise suppression, but based on the notes in the header file, I didn’t really expect it to.

This didn’t help me since I need to respond to short one word commands, but for other’s that are looking to activate and track on longer voice patterns, it might help since it would force OpenEars to listen longer for a voice before triggering. This could be beneficial to avoid frequent “Listening” states.

Also I’m finding that 2.0 for VAD is still too sensitive for me as it’s triggering on the slightest noise in the room. I’m starting at 2.5 and giving my users the option to scale up to 3.5 if they have more variable noise in their environments. This seems to be working better for me in my tests.

I’ll post back if I discover anything else of interest.
