Weird output when initializing mic, on Raspberry Pi 0W

Steps to reproduce

  1. Everytime I run this code:
    `import speech_recognition as sr
    import time
    import gpiozero as gpio
    led = gpio.PWMLED(27)
    r = sr.Recognizer()
    def Recognize():
    with sr.Microphone() as source:
    r.adjust_for_ambient_noise(source)
    print("Say something!")
    r.pause_threshold = 0.5
    audio = r.listen(source, timeout=3, phrase_time_limit=5)
    try:
    print("recognizing")
    command = r.recognize_google(audio, language= "en-in")
    print(command)
    print("Google Speech Recognition thinks you said:" + command)
    except sr.UnknownValueError:
    print("Google Speech Recognition could not understand audio")
    except sr.RequestError as e:
    print("Could not request results from Google Speech Recognition service; {0}".format(e))
    if "lumos" in command:
    if "Maxima" in command:
    led.value = 1
    else:
    led.value = 0.3
    print("Lumos")
    if "lomo" in command:
    if "Maxima" in command:
    led.value = 1
    else:
    led.value = 0.3
    print("Lumos")
    if "lumo" in command:
    if "Maxima" in command:
    led.value = 1
    else:
    led.value = 0.3
    print("Lumos")
    if "moon" in command:
    if "Maxima" in command:
    led.value = 1
    else:
    led.value = 0.3
    print("Lumos")
    if "locks" in command:
    print("nox")
    led.value = 0
    if "KNOX" in command:
    print("knox")
    led.value = 0
    if "no" in command:
    print("knox")
    led.value = 0

while True:
Recognize()`
2. I am running this on a Raspberry Pi 0 w using a bluetooth headphone microphone
Expected behaviour

It should run and listen continuously.

Actual behaviour

It is giving some weird output like this

BTW this happens everytime when "Say Something" is printed when run in loop. It delays the time it starts taking input, thus it isn't continuously listening. Is there any way to disable these info/warnings. But my mic works just fine, Thanks a lot for this great Library
