Hmm...I wrote a GUI for flite back in 2007 and it was packaged with the original flite v1.2 program on OS4Depot. That archive is no longer available so I just uploaded fliteGUI in it's own archive. It is in upload section on OS4Depot at the moment.
It supports speaking text entered into a string gadget.
Loading a text file to speak.
Saving the spoken text as a .wav file.
It also has controls for setting the speed and pitch of the voice.
Just tested it and it works fine with flite v1.4 on OS4Depot.
Just place fliteGUI in the same directory as flite.
Hope someone finds it useful.
