Converting Printed Text to Audio

I would like to scan some documents of printed text with my HP Photosmart All-in-One, convert the image to a text file and then convert the text file to audio and load that into my iPhone so that I can listen to it while I'm doing other things. The question is, are there any apps that do all of this or some set of apps to do this. I would appreciate any help you could give me.
