I use gesture recognition mediapipe and wanted to mix with `listen_in_background` function ceased to function after code modifications. The cursor movement has become slow and laggy, with pauses occurring when Speech Recognition is activated.

def callback(recognizer, audio):
    try:
        print(recognizer.recognize_google(audio))
        text = recognizer.recognize_google(audio, language = "id")
        if "Tuliskan" in text.lower():
            speak("Silahkan Bicara!")
            teks = recognizer.recognize_google(audio, language = "id")
            pyautogui.write(teks)
    except sr.UnknownValueError:
        pass

def main():
    recognizer = sr.Recognizer()
    mic = sr.Microphone(0)
    with mic as source:
        recognizer.adjust_for_ambient_noise(source)
    stop_listening = recognizer.listen_in_background(mic, callback)
    stop_listening(wait_for_stop=True)

I’ve encountered performance issues after integrating gesture recognition with the listen_in_background function for speech recognition. As a result, cursor movement has become sluggish and pauses occur during speech recognition activation. Help me to fix this code! Thanks.
