Question

当我用带有getproperty（语音）的pyttsx3模块将pdf转换为文本或将文本转换为音频文件时，出现以下错误

文件“ C：\ Users \ Sanjay \ AppData \ Local \ Programs \ Python \ Python36 \ lib \ site-packages \ pyttsx3 \ drivers \ sapi5.py”，第88行，在 返回[self._tts.GetVoices（）中attr的[self._toVoice（attr）] _toVoice中的文件“ C：\ Users \ Sanjay \ AppData \ Local \ Programs \ Python \ Python36 \ lib \ site-packages \ pyttsx3 \ drivers \ sapi5.py”，第77行 返回Voice（attr.Id，attr.GetDescription（）） _ctypes.COMError：（-2147200966，无，（无，无，无，0，无））
