хотел запустить данный код, но выдало ошибку. Не могу понять , как её решить

import pyttsx3
import speech_recognition as sr

engine = pyttsx3.init()
r = sr.Recognizer()
with sr.Microphone(device_index=11) as sourse:
    engine.say('Скажи что-нибудь')
    audio = r.listen(sourse)

query = r.recognize_google(audio, language='ru-RU')
engine.say('Вы сказали' + query.lower())
engine.runAndWait()

ошибка:
