Topic: Arduino for low-power, limited voice recognition (Read 154 times) previous topic - next topic


I wanted to prototype a voice recognition device, preferably from an Arduino Nano or Mini, if it's appropriate. Ideally it's a low-power device (charged once a day at most), and from some cursory research, it looks like even an RPI zero would draw too much current to last 24 hours without a pretty hefty battery.

I've seen some other Arduino VR projects, and I was wondering if you can cut down on the computing power required if it only needs to recognize a limited set of ten or so words ("Play" "Pause" "Rewind", etc), or is the processing needed to recognize ten words more or less the same to recognize a hundred words?= (obviously less hard drive space needed)?
