VoiceDream Scanner is an OCR, (Optical Character Recognition( app that allows you to take a picture of a document and it reads it back to you. You will most likely need the app VoiceDream Reader as well. It is very similar to the KNFBReader app, but it has been said that VoiceDream Scanner is better. I am not sure which one is better, but I am thinking of making a comparison episode at some point.
