Voice recording for association with a dot pattern for retrieval and playback

Abstract

A link table is generated, voice information is associated by dot patterns, and then, voice information associated with the dot pattern is reproduced from a speaker when the dot pattern is read by means of a scanner. In this manner, the dot pattern is printed on a surface of a material such as a picture book or a card, making it possible to play back voice information corresponding to a pattern or a story of a picture book and to play back voice information corresponding to a character described on the card. In addition, by means of a link table, new voice information can be associated with, dissociated from, or changed to, a new dot pattern.

         7 . A sound recognition system comprising:
 a sound input unit that inputs sound information; and   a medium on which a dot pattern signifying a category code is superimposed and printed with a text, figure, or icon signifying a category,   wherein an optical reading unit for reading a dot pattern reads out the dot pattern signifying the category on the medium, the dot pattern is converted into the category code (a dot code), and then, sound information input from the sound input unit is sorted out based on the category code, thereby improving accuracy of sound recognition.   
     
     
         8 . The sound recognition system according to  claim 7 , having a sound recognition circuit that analyzes the sound information and converts the sound information into text data, and the sound recognition system transmits the text data.
