SayPad

SayPad, the freeware talking text editor can read you a good book or help you write one, using SAPI 5.1 Text To Speech (included). It can convert Text to Audio for a whole book in one run, splitting off chapters into well named Audio files. You can fit huge files into it like the whole Bible for instance, (In fact it has a filter you can turn on that skips over verse numbers to let you hear it like a story.)
