MMM-Voice using Google Voice Kit HAT

@Mykle1 that might depend. I used already a usb mic array and a i2s mic array and do not really have any more lagg ;)

@maxbachmann
Sounds great…Can you mention the brand that you used, if possible? Thanks… -
@shounak78_mm
The only reason I didn’t consider this was the heat issue. How about that? I worry about it could go over 60 C. -
@maxbachmann
I just found a SEEED ReSpeaker 4 Mic Array for Raspberry Pi. Hopefully, this will be good… -
@shounak78_mm
I own the 4 mic array and it works absolutely fine and the usb mic I use is the respeaker
mic array v2 (it’s totally awesome but pretty expensive for 70$ when you do not need all the features). (the 4 mic requires a driver to run which is explained on their wiki. I guess with the google kit it works similar.)and @Sean I use the 4 mic array and I know a couple of people using the respeaker 2 mic hat which are all that close to pi. Maybe there are problems when running it at full load permanently, but at least for me thats no usual scenario :)

@maxbachmann
Thanks a ton again… -
@shounak78_mm no problem I use them quite a lot and am really happy with all my respeaker mic arrays so far. All worked pretty awesome. Obviously there are differences, but for a basic speech recognition I even know a ton of people that just use the 2 mic hat from respeaker and are happy with it :)
I myself started with a respeaker 4 mic array for the pi and now use the mic array v2 for it’s onboard speech processing. I can use it in my living room with radio on (not playing over the array) and it still removes pretty much all background music ;)
For my other rooms where I do not play radio that much I will probably just put a pi zero with a 2 mic hat or a 4mic array that streams that only does the hotword detection and then streams the audio to a main device which does the rest of the speech recognition work. -

Excellent. It has been my experience that a USB mic introduces lag, even on a quad core i7 machine. I’ve never used that array you speak of but if you’re having no lag using it on a Pi then more power to you brother.
