We present a remarkable information-carrying technology that’s had several millennia to evolve – paper and ink! Durable and cheap, easily replicated and handled in many modes, paper has--until now--been limited in one respect, it could not talk.

Through advancement in pattern scanning technology using standard cell phone camera sensor chips, printed labels can embody recorded voice and sound. This is a self-contained technology of secure, encrypted printed audio communication. It does not require external databases to retrieve sounds, so no network connectivity or separate computer is required.

Scanning can be done without contact and without critical alignment or sequence requirements. The reader/writer is a handheld device less complex than a cell phone. The functionality can in fact be implemented in a cell phone, camera, webcam-enabled PC, etc.

Where magicians used flashpaper to create a blaze of glory, Labels That Talk (LTT) now introduces the magic of Soundpaper.
