ClipSpeak is a portable, lightweight text-to-speech tool that speaks text copied to the clipboard. It is intended to be as transparent as possible to the user, keeping user interface and interaction to a minimum.
At this moment it simply uses the voice selected in the control panel's speech dialogue, but support is planned to allow voice selection in the program.
ClipSpeak is targetting the .NET Framework version 2.0, and is written in C# using Visual Studio 2008. It uses the Microsoft Speech Object Library for speech output, which means it cannot use all synthesizers available. ClipSpeak does not store any information in the registry, nor anywhere else on disk, meaning it is fully portable.
For a more in-depth description of how the program works and is structured, see the dev.txt document.
