Espeak plays the mbrola voice by its own

[muflone]

Since version 1.44 espeak plays the mbrola voices by its own instead of relying on external mbrola process.

http://espeak.sourceforge.net/mbrola.html

From eSpeak version 1.44 onwards, eSpeak calls the mbrola program directly, rather than passing phoneme data to it using a pipe.

Doing so, Gespeaker doesn't control espeak and mbrola output anymore, resulting unstoppable and unpausable.

This is in progress to be solved. The code in git already fixed this behavior. Its stable fix will be released in the 0.8.2 version
