In this podcast, Thomas Domville gives us a demonstration of Prizmo Go - Instant Text Capture, an iOS app (free with in-app purchases) which allows one to quickly and easily scan printed text and have it read aloud. From the App Store:

Aim at text. Shoot. It's yours! Prizmo Go lets you quickly grab printed text with the camera. After text is recognized in a blink of an eye, you can interact with it in many useful ways. Or just send it to other apps. And if you've got a Mac, you can even copy/paste it there (*). No more retyping. Feels like magic, just at your finger tips.

Additionally, Prizmo Go provides rich interactions with the captured text. After shooting, text from the original picture is revealed, and swiping through it allows fast and accurate text selection directly from the image. Selected text can then be read aloud, or you can tap to browse to any printed website address, call phone numbers, trigger Mail app from an email address, or even reveal physical address in Apple Maps and initiate navigation to that place.

Prizmo Go comes with enhancements specifically built for VoiceOver, in addition to spoken guidance prior to shooting. That, combined with its text-to-speech capabilities, make it a great companion in case you need help reading printed documents.
