Python Text to Speech in Macintosh

Are there any libraries in Python that does or allows Text To Speech Conversion using Mac Lion's built in text to speech engine? I did google but most are windows based. I tried pyttx. I tried to run

import pyttsx
engine = pyttsx.init()
engine.say('Sally sells seashells by the seashore.')
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

But I get these errors

File "/Users/manabchetia/Documents/Codes/Speech.py", line 2, in <module>
    engine = pyttsx.init()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/__init__.py", line 39, in init
    eng = Engine(driverName, debug)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/engine.py", line 45, in __init__
    self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/driver.py", line 64, in __init__
    self._module = __import__(name, globals(), locals(), [driverName])
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyttsx-1.0.egg/pyttsx/drivers/nsss.py", line 18, in <module>
ImportError: No module named Foundation

How do I solve these errors?

Solution

Wouldn't it be much simpler to do this?

from os import system
system('say Hello world!')

You can enter man say to see other things you can do with the say command.

However, if you want some more advanced features, importing AppKit would also be a possibility, although some Cocoa/Objective C knowledge is needed.

from AppKit import NSSpeechSynthesizer
speechSynthesizer = NSSpeechSynthesizer.alloc().initWithVoice_("com.apple.speech.synthesis.voice.Bruce")
speechSynthesizer.startSpeakingString_('Hi! Nice to meet you!')

If you would like to see more things you can do with NSSpeechSynthesizer take a look at Apple's documentation: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSSpeechSynthesizer_Class/Reference/Reference.html
