pyttsx3 cutting off last word

[Extra]

Hello,

I got my python script to work using Text-To-Speech output but when I run it, it cuts off the last word or letters.
Ex:

speak("How may I be of service?")  

Will say "How may I be of Serv-" and the "-ice" get's cut off.

Is there a way to fix this? I tried playing around with the speech rate but it didn't help.

Any help is appreciated,
Thanks.

This works perfectly on my system. Try it and let me know if it works.

import pyttsx3

speaker = pyttsx3.init ()
speaker.setProperty ('rate', 120)
speaker.say ('How may I be of service?')
speaker.runAndWait ()

EDIT : Your code runs perfectly on my system as well.

import pyttsx3
 
def speak(audio):
    engine = pyttsx3.init()
    # voices = engine.getProperty('voices')
    # engine.setProperty('voice',voices[1].id)
    engine.setProperty('rate', 125)
    engine.setProperty('volume', 1.0)
    engine.say(audio)
    engine.runAndWait()
     
speak ('How may I be of service?') 

[Extra]

speaker = pyttsx3.init ()
speaker.setProperty ('rate', 120)
speaker.say ('How may I be of service?')
speaker.runAndWait ()

Thanks, that worked!
For some strange reason engine.say() will cut it off but speaker.say() won't.

EDIT: After some quick testing It turns out that engine.setProperty('voice',voices[1].id) the voices[1].id was the issue. I changed it to voices[2].id (a female voice) and it didn't cut anything off. Still strange that voices[1].id is the only voice that cuts off the last word.

I have one other question though. Is it possible to have my speech output run as the text is being displayed on the screen (through the auto-type/typewriter animation). Right now the text will "typewrite" to the screen, then the speech output will start. Is there anyway the can work simultaneously?

This would be my best shot at that.

import sys
import time
import pyttsx3
import threading

engine = pyttsx3.init ()
engine.setProperty ('rate', 120)

def tell (*output_array) :
	output_string = ' '.join (output_array)
	engine.say (output_string)
	engine.runAndWait ()

def show_and_tell (output_string) :
		output_array = output_string.split ()
		telling = threading.Thread (target = tell, args = (output_array))
		telling.start ()
		for letter in output_string :
			print (letter, end = '')
			sys.stdout.flush ()
			time.sleep (0.08)
		print ()

show_and_tell ('How may I be of service?')
