How add WAKE-UP function in python?

Question

I have made a voice assistant with python. I wrote this code to add wake up function in my voice assistant.

WAKE = "hey jarvis"
SERVICE = authenticate_google()
print("Start")

while True:
    print("Listening...")
    text = get_audio()

if text.count(WAKE) > 0:
    speak("I am ready")
    text = get_audio()

But when I run it, I got this error:

Traceback (most recent call last):
  File "C:/Users/Faizan/Desktop/gui.py", line 62, in <module>
    query = takeCommand().lower()
  File "C:/Users/Faizan/Desktop/gui.py", line 41, in takeCommand
    with sr.Microphone () as source:
  File "C:\Users\Faizan\AppData\Local\Programs\Python\Python36\lib\site-packages\speech_recognition\__init__.py", line 86, in __init__
    device_info = audio.get_device_info_by_index(device_index) if device_index is not None else audio.get_default_input_device_info()
  File "C:\Users\Faizan\AppData\Local\Programs\Python\Python36\lib\site-packages\pyaudio.py", line 949, in get_default_input_device_info
    device_index = pa.get_default_input_device()
OSError: No Default Input Device Available

Here is my full code:

import wikipedia

from tkinter import *

Faizan_root = Tk()
Faizan_root.geometry("300x400")
Faizan_root.title("JARVIS AI by Faizan Jallani")

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[1].id)

WAKE = "hey jarvis"
SERVICE = authenticate_google()
print("Start")

while True:
    print("Listening...")
    text = get_audio()

if text.count(WAKE) > 0:
    speak("I am ready")
    text = get_audio()

engine.say(audio)
engine.runAndWait()

    hour = int(datetime.datetime.now().hour)
if hour>=0 and hour<12:
    speak("Good Morning!")

elif hour>=12 and hour<18:

else:

speak("I am JARVIS. How may I help you Sir?")

It seems like it has indentation error in with sr.Microphone() as source: you should write it under your def command function not independent. It should be like:

def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 0.8
        audio = r.listen(source)
