Hi Paula and list: You could buy a small speaker of the type that is carried by Radio Shack. I think they are called mobile speakers. It can be plugged directly into the headphone jack of the Bookport. Alternatively, you could use a patch cable to connect the headphone jack of the Bookport to the auxiliary input of a cassette player, such as the Library of Congress C1. You can then press play on the cassette player, then press the two key on the Bookport. It seems to me that this forfeits some of the convenience of the Bookport's portability, but perhaps that isn't as important to you. So go for it. Cheers, Dave
