Segfault on Ubuntu 10.10, 11.04

mrmekon commented 13 years ago

Situation:

import pyttsx pyttsx.init() Segmentation fault

Cause: In pyttsx/drivers/espeak.py, in init(), self.getProperty('voice') results in a call to GetCurrentVoice() in _espeak.py, which calls espeak_GetCurrentVoice() in libespeak.so.1. libespeak is returning a valid result with an empty name. EspeakDriver._defaultVoice gets set to None. A subsequent call to self.setProperty() references the None value, and causes a segmentation fault.

Possible solution: I know nothing of espeak or its API. Mine works, but does not return a 'current voice'. This solved the problem on my machine:

Replace line 37 of espeak.py:

EspeakDriver._defaultVoice = self.getProperty('voice')

With this block:

EspeakDriver._defaultVoice = self.getProperty('voice')
if EspeakDriver._defaultVoice == None:
    EspeakDriver._defaultVoice = "en"

This just defaults to english if espeak doesn't return a voice. Text-to-speech works as expected after this modification.

Version information: Ubuntu Server 10.10 Python 2.7 pyttsx-1.0 libespeak1 version 1.44.05~really-1.44.04-0ubuntu1

the posted fix did not work on my Ubuntu 11.04

@rodrigob the fix I just committed seems to get pyttsx working for me on Natty. Let me know if it works for you.

I do get a large batch of ALSA/Jack errors when espeak initializes, but it happens whether I'm using pyttsx or the espeak command line program directly. I think it's a consequence of running in VMWare Fusion.

the test now runs fine on my Natty machine. Thanks for the fix !

Can you upload this fixed version to PyPi?

Hi! I try use a module Chatterbot mixed with Pyttsx for do it speak the chaterbot, but the loop While cut de pronunciation of word chains, example: chatbot write: hello, computer only say "he". The example block code is:

# chatbot empiieza' while True: speak = raw_input('- ') response = chatbot.get_response(speak) # dice la respuesta print response engine.say(response) # mantiene el TTS enn marcha engine.runAndWait()`
