如何修复 python 3.8 中的 pyttsx3 模块错误

Question

While using the pyttsx3 module in my python 3.8.5 virtual environment by this code:

import pyttsx3

def speak(speak):
    engine = pyttsx3.init()
    voices = engine.getProperty('voices')
    engine.setProperty('voice', voices[1].id)
    engine.getProperty('rate')
    engine.setProperty('rate', 155)
    engine.say(speak)
    engine.runAndWait()

speak("Hello")

I'm getting this error on compilation of the above code:

Traceback (most recent call last):
  File "D:\virtualenv\venv\lib\site-packages\pyttsx3\__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "c:\users\CurrentUser\appdata\local\programs\python\python38-32\lib\weakref.py", line 131, in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

Everytime I run the given python code, the above error occurs and I'm using VS code as my coding IDE in Windows 10

Answer 1

Take the pyttsx3.init() out of the function. It is not to called repeateadly. It is to be called only once.

import pyttsx3
engine = pyttsx3.init()
def speak(word):
   #set engine properties
   engine.say(word)
   engine.runAndWait()

speak('Speak')

Answer 2

This should work:

import pyttsx3
engine = pyttsx3.init()

def speak(word):
    voices = engine.getProperty('voices')
    engine.setProperty('voice', voices[1].id)
    rate = engine.getProperty('rate')
    engine.setProperty('rate', 155)
    engine.say(word)
    engine.runAndWait()

speak("Hello")
