Recording audio from microphone in Python

I'm trying to create a virtual assistant in python, which works using speech recognition. While running the program though, it isn't taking any voice input, though there are no errors. My microphone is properly connected and I'm pretty sure there is something wrong with the code. Please help me with this.

# Import packages
import speech_recognition as sr

from gtts import gTTS

# Ignore any warning messages

# Record audio and return as string 
def recordAudio():

    # record the audio
    r = sr.Recognizer() #creating a speech recognizer

    # open the microphone and start recording
    with sr.Microphone() as source:
        print('Hello! How may I help you?')
        audio = r.listen(source)
    # Use google speech recognition
    data = ''
    try:
        data = r.recognize_google(audio)
        print('You said : '+data)
    except sr.UnknownValueError : 
        print("Sorry, I didn't quite understand that")

    myobj.save('assistant_response.mp3')

    for phrase in WAKE_WORDS:
        if phrase in text:
            return True
        else: return False

    #If The wake word is not found in text from the loop , so it returns False

    ordinalNumbers = [ '1st', '2nd', '3rd', ' 4th', '5th', '6th', '7th', '8th', '9th', '10th', '11th', '12th', '13th', '14th', '15th', '16th',

    return 'Today is '+weekday+' '+month_names[monthNum - 1]+' the '+ ordinalNumbers[dayNum -1]+' .'

#Function to return greeting
def greeting(text):

    #Greeting inputs
    GREETING_INPUTS = ['Hi!', 'Hey!', 'Hola!', 'Wassup?', 'Hello!']

    #Greeting response
    GREETING_RESPONSES = ['Howdy', 'All that good', 'Hello master', 'Hey there!']

    #If users input is a greeting, then return a randomly chosen greetng response
    for word in text.split():
        if word.lower() in GREETING_INPUTS:
            return random.choice(GREETING_RESPONSES)
    
    #If no greeting was detected
    return ''

#A functions to get persons name from text
def getPerson(text):

    wordList = text.split() #splits the text to words

    for i in range(0, len(wordList)):
        if i+3 <= len(wordList)-1 and wordList[i].lower() == 'who' and wordList[i+1].lower() == 'is':
            return wordList[i+2] + ' '+ wordList[i+3]

while True:

    #record the audio
    text = recordAudio()
    response = '' 

    #check for the wake word / phrase
    if (wakeWord(text) == True):
        
        #check for greetings by the user
        response = response + greeting(text)

        #check to see if the user has said anything about data
        if('date' in text):
            get_date = getDate()
            response = response + ' '+get_date

        #check to see if the user said 'who is' 
        if('who is' in text):
            person = getPerson(text) 
            wiki = wikipedia.summary(person, sentences=4)
            response = response +' '+ wiki

        #assistant responds back using audio and text from response
        assistantResponse(response)

I think the problem is that the wake word should be lowered (Python is case-sensitive)

BTW, check out my Virtual Assistant, Ida

# A function for wake word
def wakeWord(text):
    WAKE_WORDS = {'Hey Jarvis', 'Jarvis', 'Hello Jarvis', 'I need help'} #list of wake words

    text = text.lower() #convert the text to lower case words

    #Check to see if user input is a wake word
    for phrase in WAKE_WORDS:
        if phrase.lower() in text: #convert the phrase to lower case words as well
            return True
        else: return False
