I created a small function that converts string to speech and saves to a .mp3 file.
This works without any issues on main thread. But when I run this function on second thread it doesn't generate any .mp3 file and doesn't raise any error. Do you have any idea what could cause that?
Edit: I realized that I have never initialized text_to_speech.py, only ran the function.
File with text-to-speech function:
# text_to_speech.py
import pyttsx3
engine = pyttsx3.init()
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[3].id)
engine.runAndWait()
def tts_to_file(text_string, save_file_path):
engine.save_to_file(text_string, save_file_path)
engine.runAndWait()
Main thread (works):
# main_file.py
from text_to_speech import tts_to_file
tts_to_file("Hello world", "./test.mp3")
Main thread (doesn't work):
# main_file.py
from text_to_speech import tts_to_file
from threading import Thread
p = Thread(target = tts_to_file, args = ("Hello world", "./test.mp3"))
p.start()
p.join()
# This doesn't do anything and raises no errors
