Pyttsx3 works on 32bit-Python but not on 64bit-Python

Situation

I am using the pyttsx3 module for my Alexa-like project. The source code I wrote all worked fine on my own PC, but now I am trying to get this thing to work on a Pi.

• System : Raspberry Pi 4GB (64-bit quad-core processor)
• OS : Windows 10 Pro from the WoR project
• Python version : 3.9.1 (64bit) & 3.6.0 (32bit)

Source code:

import pyttsx3

engine = pyttsx3.init()
nl_voice_id = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\MSTTS_V110_nlNL_Frank" # Dutch Voice..
voices = engine.getProperty('voices')
engine.setProperty('voice', nl_voice_id)

def talk(text):
    engine.say(text)
    engine.runAndWait()

talk('test')

Nothing special but when I run this code on a 64-bit based Python version I get this error:

Traceback (most recent call last):

What caught my eye was the last line: OSError: [WinError -2147024703] %1 is not a valid Win32 application

So I tried running the exact same program with a 32bit Python version. This worked. But I need this to work on 64bit because I have some other modules installed in my real program that else won't work properly.

• I already have pypiwin32 installed.
• I already have pywin32 installed.

I also tried to uninstall pytts3x and install the 2.71 version with pip install pyttsx3==2.71, this gave me a pywintypes_com error.

I tried this solution to solve this pywintypes error, but no luck.

What more can I try?

Edit:

When I installed Raspbian (32bit) on the Pi, I, unfortunately, got the same error. I think Pyttsx3 is a really good module but not for the Pi. So I did some research to find another Text-to-Speech (TTS) module for Python. I came across gTTS, which is also a great module and easy to integrate. It uses Google translate, so you can choose from each Google Translate language.

This is my workaround for now. If anyone has an answer to why pyttsx3 ain't working on a Pi, let me know. Although gTTS is great, I like Sapi5 more.
