There is no specific GUI for festival, but if you want to have text read out Orca, the screen-reader built into Ubuntu can use the festival voices if you open the preferences page and select it after starting Orca. Orca comes with espeak already and I am sure this already has a hindi voice etc. The other approach would be to install Kubuntu instead of Ubuntu, which has its own text to speech applications that can also use festival if you want. You do not say want you actually want to do so it is difficlut to give you any more specific advice! The simplest solution would be to use Ubuntu , Orca and Espeak!
drbongo Or You could do as I did. i'm using gnome window manager and it's desktop and in it, i'm using the "KDE Text-to-speech Manager"- the KDE Text-to-Speech system - is a plugin based service that allows any KDE (or non-KDE) application to speak using the DCOP interface. . It's easy to set it up to use festival for speech output.see http://ubuntuforums.org/showpost.php?p=6834855&postcount=6
