This is a simple wrapper app for OS X Speech Synthesis function, via the QCPlugin Speech Synthesis project.
This makes it easy to get that function without having to install QC, and is generally a very basic app.
Input text and Voice style are able to be selected via Command+i, or the app's menubar. The app will remember the last text that has been input, and you can enable the voice or restart the speaking by toggling the Enable parameter. There's a simple spectrum meter included.
