aloud

Can I make an audiobook from a PDF or a DOC file??? I ask this coz the adobe reader has a read aloud feature. can i do something using that.

there was a software given by digit few years ago ( at least 3 yrs ago ) which can read aloud any text . But now I forgot which yrs' which month it was given . But I need the same software . Its advantage was it can read any amount ...like u can read aloud a total ebook . it was a demo ...
