Question

因此，基本上我是在虚拟环境中构建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（）会收到错误

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()

进行研究后，我发现使用pyttsx3.init（“ dummy”）不会产生任何错误。但是，下一个问题是当我运行

时

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

我什么也没听到或看到任何错误

我应该注意，如果我在虚拟环境之外的pyttsx3.init中使用上面的代码时没有虚拟对象，那么一切正常。

Answer 1

尝试一下：

import pyttsx3
from pyttsx3.drivers import sapi5

engine = pyttsx3.init('sapi5')
engine.say('hey')
engine.runAndWait()

Answer 2

我在 1 个月前遇到了同样的错误。我犯的错误是我最初安装了 python X36 版本。这就是原因。检查python架构使用下面的代码

src\4-4-project>python
>>import platform
>>platform.architecture()

如果输出显示 32 位而不是 64 位，则卸载 python X36bit 并全新安装 python X64。不过不要担心预装的软件包。您只需通过以下代码保存所有包

pip freeze > packages.txt
#or
python -m pip freeze> packages.txt

安装python x64bit版本后，您可以通过以下代码重新安装所有软件包

python -m pip install -r packages.txt

设置python x64bit版本并设置路径后，下面的代码就足够了。不要忘记再次安装软件包。

import pyttsx3
engine = pyttsx3.init()
engine.say("hello world")
engine.runAndWait()

希望它有效。
