Python Standalone Executable file does not run and shows error in Command Prompt

Question

As I am new in Python, I made a VOICE ASSISTANT by Python in Pycharm. I only write the code and run I in the pycharm, it ran smoothly. I haven't made any GUI for it. I just converted the code in the EXE file by using the Pyinstaller. when I run the exe file, it has shown me this error in Command Prompt.

Traceback (most recent call last):
  File "site-packages\pyttsx3\__init__.py", line 20, in init
  File "c:\users\faizan\appdata\local\programs\python\python36\lib\weakref.py", line 131, in 
__getitem__
    o = self.data[key]()
KeyError: 'sapi5'

During handling of the above exception, another exception occurred:

Use hidden import to specify the module while creating exe,

$ pyinstaller --hidden-import=pyttsx3.drivers yourscript.py
