How to stop speech recognition after the desired "phrase"?

Question

Python

I am making a voice assistant and I want that after a certain phrase, all commands will stop being executed until I say the same phrase. I made such a function, but if you REPEATEDly say the desired """phrase""", then nothing works. We need to do something with the second """for""". What needs to be changed? I can explain the code if needed.

def stop():
    global text, tr
    tr = 0
    variants1 = ['остановись', 'так приостановись', 'игнорь щас', 'выключи распознавание', 'не слушай плиз']
    for z in variants1:
        if (z in text)&(tr == 0):
            word = text
            word = word.replace('остановись','')
            word = word.replace('так приостановись','')
            word = word.replace('игнорь щас','')
            word = word.replace('выключи распознавание','')
            word = word.replace('не слушай плиз','')
            commands.clear()
            commands.append(word)
            variants2 = [word]
    for v in variants2:
        if (v in text)&(tr == 0):
            commands.remove(word)
            commands.extend(commands1)
    tr = 1
    text = ''
