pyttsx3在python 3.7上不起作用，未找到模块

Question

我使用以下代码收到以下错误

import speech_recognition as sr
import pyttsx3

engine = pyttsx3.init()
engine.runAndWait
engine.say("Hello")

  Traceback (most recent call last):
       File "C:\Users\ProBook\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\LocalCache\local-packages\Python37\site-packages\pyttsx3\__init__.py",
 line 20, in init
         eng = _activeEngines[driverName]
       File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.7_3.7.1776.0_x64__qbz5n2kfra8p0\lib\weakref.py",
 line 137, in \_\_getitem\_\_
         o = self.data[key]()
     KeyError: None

在处理以上异常期间，发生了另一个异常：

         engine = pyttsx3.init()

 line 5, in <module>
         import win32api, sys, os
     ImportError: DLL load failed: The specified module could not be found.

有人对此有解决方案吗？我已经尝试过几次安装和重新安装软件包以及python

Answer 1

似乎缺少默认的sapi5引擎。尝试明确指定语言引擎。

pyttsx3.init("sapi5")

如果问题仍然存在，请尝试安装espeak并使用它初始化pyttsx。更多信息there
