Pyttsx3 Will only Speak Once

Question

When running the following program:

import multiprocessing
import pyttsx3
from multiprocessing import Process


class _TTS:

   def __init__(self):
        self.engine = pyttsx3.init('espeak')
        self.engine.setProperty('rate', 175)

   def start(self,text_):
        self.engine.say(text_)
        self.engine.runAndWait()

def Speakit(words):
    print('running Speakit')
    
    tts = _TTS()
    tts.start(words)
    del(tts)

def testing(n):
    print(n)
    if n == 0:
        words = 'Argument is zero'
        Speakit(words)
        print(words)
    else:
        words = 'Argument is not zero'
        Speakit(words)
        print(words)

if __name__=="__main__":
   words = 'start'
 #  Speakit(words)
   p1=Process(target=testing,args=(0,))
   p1.start()
   p1.join()
   p2=Process(target=testing,args=(5,))
   p2.start()
   p2.join()
   print("We're done")

If I comment out the Speakit in the main, the script run correctly, speaking what prints out

Watson $ python3 mp2.py
0
running Speakit
Argument is zero
5
running Speakit
Argument is not zero
We're done

It I don't comment out the Speakit in the main, the script will just speak the "Start" word and then not speak again and just hangs

 python3 mp2.py
running Speakit
0
running Speakit

Don't understand why

Answer 1

I have given your code a quick spin. At first, the interpreter threw some major errors due to the initialisation of your pyttsx engine. I deleted the 'espeak' argument and then it did work and the program also did speak both lines.

Maybe use try/except in order to troubleshoot.
