import speech_recognition as sr

listener= sr.Recognizer()
try:
    with sr.Microphone() as source:
        print("hai say something...")
        voice = listener.listen(source)
        command = listener.recognize_google(voice)
        print(command)
except:
    pass

This is my code. when i try to run this it shows the following error

ALSA lib pcm_dsnoop.c:641:(snd_pcm_dsnoop_open) unable to open slave

On Debian OS, this command solved the problem:

sudo apt-get install alsa-utils

import speech_recognition as sr

r = sr.Recognizer()
m = sr.Microphone()

try:
    print("A moment of silence, please...")
    with m as source: r.adjust_for_ambient_noise(source)
    print("Set minimum energy threshold to {}".format(r.energy_threshold))
    while True:
        print("Say something!")
        with m as source: audio = r.listen(source)
        print("Got it! Now to recognize it...")
        try:
            # recognize speech using Google Speech Recognition
            value = r.recognize_google(audio)

            # we need some special handling here to correctly print unicode characters to standard output
            if str is bytes:  # this version of Python uses bytes for strings (Python 2)
                print(u"You said {}".format(value).encode("utf-8"))
            else:  # this version of Python uses unicode for strings (Python 3+)
                print("You said {}".format(value))
        except sr.UnknownValueError:
            print("Oops! Didn't catch that")
        except sr.RequestError as e:
            print("Uh oh! Couldn't request results from Google Speech Recognition service; {0}".format(e))
except KeyboardInterrupt:
    pass

this code will work, but the ALSA errors will be still there. i dont know why.
