“Free Balabolka will open unprotected ePub files (and pdfs), but not protected ones like library books. Balabolka has options for changing font style, colour, size and background colour. It can use the free MS voices or any voices you have with other programs, and speaks with highlighting. It does not preserve presentation or images.”
The on-screen text can be saved as a WAV, MP3, MP4, OGG or WMA file. The program can read the clipboard content, view the text from CHM, DjVu, DOC, EPUB, FB2, HTML, ODT, PDF and RTF files.
Here is a video with Craig Mill showing the use of Balabolka being used with MyStudyBar
