AbstractA learning and identification support system for birders and such comprising, a media having a plurality of visually recognizable bird pictures thereon associated with respective ones of a plurality of birds to have birdsong associated therewith. A plurality of scannable barcodes are disposed on the media and associated with respective ones of the bird pictures. Each of the plurality of scannable barcodes comprises a unique index indicating the one of the bird pictures with which it is associated. A barcode scanner is used for scanning individual selected ones of the barcodes to obtain an electrical signal at an output thereof containing the unique index. There is a Compact Disc (CD) containing a plurality of birdsongs associated with respective ones of the plurality of birds, each of the plurality of birdsongs being individually addressable by means of a unique index associated therewith. There is also a CD player for playing the CD to output digital data streams reflecting selected ones of the birdsongs as well as a headset or speaker connected to the Compact Disc player means for reproducing birdsongs from the digital data streams. A data compression technique is employed which permits the system to be used for " talking book" applications with as much as nine hours of playing from a single CD. An interactive audio system configuration of the invention is also shown which can improve language learning and provide an environment for interactive audio adventures.
