[Question] "Text to Speech" doesn't work When executing the executable file,

[jjjunehkim]

Question

I used the "flet build windows --include-packages flet_video flet_audio" command to create an executable file that runs the "video", "audio" and "text to speech" functions.

<>
flet build windows --include-packages flet_video flet_audio

<<requirements.txt>>
flet==0.22.*
pyttsx3==2.90

The executable file was created without errors.
But
"Video" -> Work
"Audio" -> Work
"Text to Speech" -> Do not work

I installed "pyttsx3" for "Text to speech".
I understand that "pyttsx3"is a pure library.
So I thought the executable file would operate normally,
But it does not.
Please help for some reason.

from datetime import datetime

import flet as ft
import pyttsx3

engine = pyttsx3.init()


def say(e, audio, text):
    try:
        print(text)
        file_name = f"tts_{datetime.now().strftime('%Y%m%d%H%M%S')}.wav"

        # Create Audio File
        engine.save_to_file(text, file_name)
        engine.runAndWait()

        # Update Audio Controller
        audio.src = file_name
        audio.update()
        audio.play()

    except Exception as e:
        print(e)


def main(page: ft.Page):
    page.vertical_alignment = ft.MainAxisAlignment.CENTER
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.window_width = 400
    page.window_height = 400

    # Initial Audio,
    # !!! Must Set on_seek_complete to release the audio !!!
    audio = ft.Audio("tts.wav", on_seek_complete=lambda _: audio.release())
    page.overlay.append(audio)

    input_text = ft.TextField(label="TTS", value="Testing TTS.")

    base_column = ft.Column(
        controls=[
            input_text,
            ft.ElevatedButton(
                text="Say", on_click=lambda e: say(e, audio, input_text.value)
            ),
        ]
    )

    page.add(
        ft.Container(
            content=base_column,
        )
    )


ft.app(target=main, assets_dir="assets")

There should be a way to create an audio file with the pyttsx package and play it with ft.Audio.

However, when I build using this approach, I get an error about the pywin32 module, so I think I need to use a different tts package.
