在虚拟环境中使用pyttsx3和python解决声音问题

Question

因此，基本上我正在虚拟环境中构建一个python虚拟助手软件，我想使用pyttsx3将文本转换为语音。第一个问题是，如果我运行pyttsx3.init（），我会得到一个错误

o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File ".\__init__.py", line 3, in <module>
    init_speech()
  File "C:\Users\DJETHA\eclipse-workspace\PythonFull\PythonProjects\Betax\index.py", line 31, in init_speech
    engine = pyttsx3.init()

在做研究时，我发现使用pyttsx3.init（“dummy”）不会产生任何错误。下一个问题是当我跑步的时候

engine =pyttsx3.init("dummy")
engine.say("hey")
engine.runAndWait()

我没有听到任何声音，也没有看到任何错误

我应该注意到，如果我在虚拟环境之外的pyttsx3.init中使用了上面的代码，而没有使用伪代码，那么一切都正常。你知道吗
