Voice barcode scan device

摘要

A voice barcode scan device includes a barcode scan unit, a microprocessor, a memory unit, a voice-processing unit and a voice output unit. The memory unit stores different voice signals according to different addresses. The barcode scan unit reads the address from the barcode label and fetches the corresponding digital voice signals from the memory unit. The accessed voice signals are processed and converted to analog signals by the voice-processing unit. The analog voice signals are output from the speaker or earphones to achieve the voice education, entertainment or security purposes.
