Jan-26-2022, 02:15 PM (This post was last modified: Jan-26-2022, 02:15 PM by Extra.)
Hello,

I'm trying run my code on my Rpi 3 Which uses Debian OS. Prior to this, my code was running on my Rpi 4 which used Manjaro (Arch-linux) as an OS.
With Manjaro on my Rpi4 all I had to do was plug in my usb mic and my script would run flawlessly.

Now, on my Rpi 3, I plug in the same usb mic and it doesn't work (won't recognize any voice input).

I defined the mic and I know the mic's not broken, so how do I fix this?

I appreciate any help.

Thanks in advance.


My Code:
#!/usr/bin/env python3

import time
import sys
import wikipedia
import wolframalpha
import pyttsx3
import speech_recognition as sr 
#from Animations import startupAnimation

#-------------------------------------------------------------------------------------

#-------------------------------------------------------------------------------------
Commander = "Commander"
AI_Name = 'Baxter'
#-------------------------------------------------------------------------------------


def listenCommand():
    command=0
    hear = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = hear.listen(source)  
    #---------------------------
    # Uses google API to listen
    try:
        print("Recognizing...")
        command = hear.recognize_google(audio, language='en-in')
        print(f'{Commander} : {command}\n')
    #--------------------------------

    except:
            pass

    return command

I have audacity downloaded on the Rpi and I used it to test the mic and can record my voice and play it back, so I know it work. I even defined my sound card and device number (2,0) in: 
Output:
nano /home/pi/.asoundrc

Output:
pcm.!default {
  type asym
  capture.pcm "mic"
}
pcm.mic {
  type plug
  slave {
    pcm "hw:2,0"
  }
}
So I still don't get why my python code's not working, (I still get the same output from my 1st post, and my commands aren't being processed).
I'm completely stumped right now.
