I’ve read different things one says it recognizes the activation word as well as google home the other says you have to shout at the microphone, what’s right?
I used a ps3 eye to start with, it was fine in the same room with precise. The pocketsphinx listener isn’t as good and might have been the source of some issues, though. Try it out and see how it works for you.
The beamforming, tracking, AEC Sony software resides in the PS3 not the usb mic/cam.
Its a old cam with 4 mics that are no different than having a single mic if you don’t have the software to use the array.
There is no working opensource beamforming, tracking and AEC do exist and any mic without will not work well in the presence of loud music.
