Comment(by humitos):

 I don't have the solution yet, but I found some differences between 12.1.0
 (working) and 13.1.0 (not working) with the same Speak version:

  * XO-1.75, 12.1.0 os21
    * Speak v42 works properly
    * I can import gst espeak plugin
 {{{
 >>> import gst
 >>> gst.element_factory_make('espeak')
 <__main__.GstEspeak object (espeak0) at 0x1a20cd0>
 }}}
    * RPM: gstreamer-plugins-espeak-0.3.5-2.fc17.i686

  * XO-1.5, 13.1.0 os6
    * Speak v42 does not work (CPU issue)
    * I can't import gst espeak plugin
 {{{
 >>> import gst
 >>> gst.element_factory_make('espeak')
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 gst.ElementNotFoundError: espeak
 }}}
    * RPM: gstreamer-plugins-espeak-0.4.0-1.fc18.i686

  * Desktop, Fedora 17. sugar-build
    * Speak v42 works properly
    * RPM: gstreamer-plugins-espeak-0.3.5-2.fc17.x86_64
    * I can import gst espeak plugin
