trato de solucionar pero no me sale
You tried to solve what? You haven’t given any details of what you were doing.
Have you installed pywin32?
py -m pip install pywin32
(The PyPI page for pyttsx3 says to install “pypiwin32”, but that’s very old and obsolete; install “pywin32” instead.)
After installing pywin32, did you also run the post-install script?
It’s explained here:
