TypeIt ReadIt

With a simple interface and the ability to export your writing to a text or WAV file, TypeIt ReadIt is a great free program. Paste any text into its window, or open a TXT file directly. If you want something read to you quickly, this is a great app to try.

The interface is simple yet functional, though it is a little odd how the buttons scale if you make the window bigger. The software uses the voices that come with Windows. Use this app if you want something simple and free.
