Which microphone to use for voice recognition?

Just as the title states, which microphone is the best for room voice recognition?

I would like to suggest that you take a look at conference microphones.

Reviving because I have the same question. I’ve purchased a cheap usb and a more expensive conference usb microphone. Both are rather hard of hearing. I can record sound but when I play it back it is very muffled unless I’m speaking directly into the microphone from about 4 inches away. Has anyone had good success with any particular microphone? I want to use Snips to control my media center. Thanks!

Found this… not many devices tested and only a few rather expensive ones recommended. I can attest that the “CMTECK USB Desktop Computer CM001” does NOT work well with the raspberry pi. You need to speak within about 6 inches of the mic for it to pick anything up.
