save_to_file doesn't work when using dummy driver

[P4RZ1V4L-93]

I'm trying to run pyttsx in replit.com and when using engine = pyttsx.init() it gives

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/pyttsx3/__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "/usr/lib/python3.8/weakref.py", line 131, in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "main.py", line 7, in <module>
    engine = pyttsx3.init()
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/pyttsx3/__init__.py", line 22, in init
    eng = Engine(driverName, debug)

    self._handle = _dlopen(self._name, mode)
OSError: libespeak.so.1: cannot open shared object file: No such file or directory

so i used engine = pyttsx3.init('dummy')
engine.say('hello') works but when using engine.save_to_file('heelo' , 'hello.mp3')
it gives error

Ignoring exception in command play:
Traceback (most recent call last):

    ret = await coro(*args, **kwargs)

    engine.save_to_file('hello', 'hello.mp3')

    self._push(self._driver.save_to_file, (text, filename), name)
AttributeError: 'DummyDriver' object has no attribute 'save_to_file'

The above exception was the direct cause of the following exception:

You can install pyttsx3==2.71 to solve this problem, I did and succeeded
