gnome-speech-dectalk 1:0.4.16-0ubuntu1 (i386 binary) in ubuntu gutsy

 The GNOME Speech library gives a simple yet general API for programs
 to convert text into speech, as well as speech input.
 .
 This package provides the source code required to compile a driver
 for the commercial DECtalk software speech synthesis engine and voices from
 Fonix (http://www.fonix.com/).
 Upon installation, it will automatically attempt to compile and install
 the dectalk-synthesis-driver binary required to use GNOME Speech with
 dectalk.
 .
 Important: This package is only useful if you have already downloaded and
 installed the dectalk engine on your computer.
