I am creating a virtual assistant with Python, and when I do the part where it prints everything I speak, the code runs without errors:

import speech_recognition as sr

listener = sr.Recognizer()
try:
    with sr.Microphone() as source:
    print("listening...")
    voice = listener.listen(source)
    command = listener.recognize_google(voice)
    command = command.lower()
    if 'alexa' in command:
        print(command)
except:
    pass

But when I want to add the code which will make the virtual assistant speak, it shows errors:

import speech_recognition as sr
import pyttsx3

listener = sr.Recognizer()
engine = pyttsx3.init()
engine.say('I am alexa')
engine.say('What can I do for you?')
engine.runAndWait()
try:
    with sr.Microphone() as source:
        print("listening...")
        voice = listener.listen(source)
        command = listener.recognize_google(voice)
        command = command.lower()
        if 'alexa' in command:
            print(command)
except:
    pass

This is the error:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

  • copy/pasted your code and I cannot repro. Using latest versions for both packages (eg no package specified in `requirements.txt`), and using `python 3.9.10`. Suggest you kill your virtualenv and reinstall both packages... – Edo Akse Mar 09 '22 at 17:50
  • [This](https://stackoverflow.com/a/67674044/9267296) might be useful though – Edo Akse Mar 09 '22 at 17:52
  • which packages should I reinstall? – Edvin Parmeza Mar 09 '22 at 17:57
  • so I hope you're using a `virtualenv`. If not, start doing so now. Read up [here](https://realpython.com/python-virtual-environments-a-primer/). That being said, the package giving the issue is likely the `pyttsx3` one. – Edo Akse Mar 09 '22 at 18:01
  • I am using Pycharm...I installed virtual env...should I create a new directory? I already have one directory, which is the project I am working on – Edvin Parmeza Mar 09 '22 at 19:17
  • are you actually using a virtualenv? If your answer to this is *I don't know*, please read up on what it does and how to use it. If you *are* using a virtualenv, my suggestion would be to deactivate it, completely remove it, create a new virtualenv, activate it, and reinstall the packages you're using. The good old *have you tried turning it off and on again* fixes so many issues... – Edo Akse Mar 09 '22 at 23:58
