Karen, this is easy. I just put the whole Treasure Island into very old Macs, and it could read it aloud just fine, although with a sort of funny accent.
More modern computers read better.
If you have PCs, it's harder, but Dragon NaturallySpeaking can read text, although with a very strange British accent. Just scan it in or get it digitally off the Web, paste it into NaturallySpeaking, and have it Read Text, after selecting what you want. I am a special education teacher for 4th to 6th graders. I teach really smart kids who are very low readers. All they need is to be able to see the text read.
