Abstract
Abstract A language learning apparatus using optical code as input medium is disclosed. An optical code/bar code is associated with each of a number of words, sentences, animal cries and sounds of music instruments. The pronunciations of the words and sentences, the animal cries and the sounds of the music instruments are digitalized and stored in storage memory in advance. An optical code reader is used to converted the optical codes into an associated electrical signal which is then converted into memory address pointed to the associated digital sound data stored in the storage memory. The digital sound data are then accessed by using the memory address and converted into an analog signal to be spoken out by a loudspeaker system. The digital sound data may comprise the pronunciations of more than one language so as to enhance the learning of different languages in an interactive manner.
