Возникла проблема, в том что при конвертировании python файла в exe файл не получается загрузить пакет "pyttsx3.drivers"

Да, знаю что ответ нужно искать в документации, но прочитав о добавление пакетов толком не чего не понял.

Traceback (most recent call last):

  File "pyttsx3\__init__.py", line 20, in init
  File "c:\users\user\appdata\local\programs\python\python39\lib\weakref.py", line 134, in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:
