I am trying to make a speech recognition system on a Raspberry Pi 3 model B+ using Python. It needs a microphone. I have the keyes Sound sensor which looks like this(https://cutt.ly/Jjp9jWP). Can this sensor be used as a Michrophone?
Note:- I am very new to raspberry pi so this may sound like a silly question but please give me some knowledge
Do I need to buy a usb microphone or will this work?
