I've been trying out the demo and beta versions of TextAloud, but am disappointed with the PDF support.
As a student I need to read a lot of books, so being able to convert PDF eBooks into MP3 files is essential. However, when I try to use TextAloud to open a PDF, I get lots of bad characters in the display.
Can you add PDF support like Starfield Reader? (http://www.starfieldsoftware.co.uk) - it doesn't have many of the features of TextAloud, but can read and select sections of PDF files perfectly.
