I'll look into what options are available for changing the voice in text to speech, but I'm sure it will only match "closest" to existing voice agents built into windows.
Made some updates today, so go ahead and download version 22b. I fixed some problems found between free and premium versions (so now I can temporarily grant premium version to people if I want), as well as made a notification when a baddie report (i.e. how many people failed at Emperors Blade Dance or did fire damage on Yakhmar) is ready.
