I have a text-to-speech reader 'Digalo', which I nicknamed Smokey Gordon. I have had him since Windows Millenium so he is very old and by the timbre of his voice he is obviously a heavy smoker. In Vista he is rather unstable and cannot cope with PC hibernation. Smokey Gordon does about 95% of my web reading and I have found TTS an indispensable aid to covering large amounts of material and proof reading.
So I thought I would have a go at making a new clipboard speaker now that we can access all the necessary components. This example is a combination of COM/SAPI 5, Opengl threading and Clipboard. Unfortunately some of the components of SAPI are not available under Wine, and also the Windows-XP voice 'Sam' is very rough. So this is only suitable for Vista and Windows 7.
The is example is minimal. when you click on it, the text contents of the clipboard will be spoken by the 'Anna' voice.
I include this in examples/sound (Oxygen in-progress version)
