Recording audio from microphone in Python

Question

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.

    # open the microphone and start recording

Answer 1

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
