Voice commands. How to?

Someone asked me about using voice commands as a trigger. They said they’d like to speak 12’ away from the sensor. I have never looked into this. Can this be done at that distance? It seems rather far.

MicroCenter currently has the for $4.99, you also need a RaspberryPi 3.

I bought one last week but have not used it yet.

I have the new generation kit. Accurate voice commands at 12 feet (without shouting) might be a challenge in a room with significant background noise. As packaged, the kit uses the big button as the trigger. You can replace that for hands-off activation.
Kinda like my wife. Without her, I'd never know if I was driving too fast, had the air conditioner on too high, etc...
Alexa/Echo Dot is simply amazing. Its microphone array not only hears and understands while it's talking/playing/alarming, but it detects the direction of the sound source.
Now THAT's some magic smoke in there.
Haven't tried, so I can't say how good or (more likely) bad they are.
But it just HAS to be better than the VCP200 voice recognition chips I got from Radio Shack back in the 1988: https://www.ebay.com/itm/Radio-Shack-Archer-276-1308-Voice-Recognition-IC-VCP200-Tandy-NOS-Vintage-1988/282976262537
Speaker independent, and VERY few commands. Your choice of:
1) Yes/No or On/Off Just two choices, more reliable than...
2) Go, Stop, Left Turn, Turn right, Reverse
They do work, but you need to practice saying the words in a way the chip likes. Watch EEVblog Dave test it at 19:00:
I tried doing some searches but com up with little regarding the schematics of the pill bottle mics of the old days. It's becoming a lost art!
