DFRobot and raspberry pi 4 communication problems

I bought the DFRobot voice recognition module, I tried with arduino and work perfectly but I try to use with a raspberry pi 4 and doesn’t work I already tried different scrip and nothing work and I can see that the DFRobot is properly connected to the raspberry pi beca I see it in the terminal it show like 064 something like that, but when I say a command nothing happen.
