Workaround for pyttsx engine runAndWait not returning on Yosemite

Question

The python module pyttsx is a text-to-speech module for python. The sample code

import pyttsx
engine=pyttsx.init()
engine.say("hello")
engine.say("everybody")
engine.runAndWait()

is supposed to get the the call to runAndWait and read the queue words ("hello" and "everybody") and then return. However on Yosemite the runAndWait function never returns (just hangs forever) even after the queue of words is read.

I'm pretty sure this is just a Yosemite problem. Any mac users out there have a workaround for this issue yet? Thanks very much.

Cheers, ht

Answer 1

To deal with this problem,
1- make a class for pyttsx3;
2- make an instance of the class, send the text to it, then del() it.
3- repeat step 2 several times.

the Class:

import pyttsx3

class _TTS:

    engine = None
    rate = None
    def __init__(self):
        self.engine = pyttsx3.init()


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

the instance:

 tts = _TTS()
 tts.start("text")
 del(tts)
