How do I update the value of the textbox in this code?

Question

I'm using Tkinter to design a basic front end for my app

global TextBoxText 
TextBoxText = "Waiting for audio..."

I've created a global variable and set a default value to it above

def buttonClick():
    r = sr.Recognizer()
    global TextBoxText
    with sr.Microphone() as source:
        print("listening.....")
        r.pause_threshold = 1
        audio = r.listen(source)
        TextBoxText = "Listening to audio..."

    try:
        print("Recognizing.....")
        query = r.recognize_google(audio, language='en-in')
        print(f"user said {query}\n")
        TextBoxText = query

    except Exception as e:
        print("say that again please.....")
        TextBoxText = "Could not catch that :(" + '\n' + "Press the button to speak again"

In this function, I'm updating TextBoxText's value to different strings so that when the button is clicked, it can update the value accordingly.

ListenButton = Button(root, text="Start listening?", fg='white', bg = '#56717d', font= ('Helvetica', 11), command= buttonClick)

When ListenButton is pressed, it will execute the code in the function and update the value of TextBoxText too

TranslatedText = Text(root, height= 10, width= 40)
TranslatedText.insert('end', TextBoxText)
TranslatedText.config(state= 'disabled')

Unfortunately, I am not able to figure out how to display the updated text in TranslatedText. If you could help me out, I'd be really grateful
