PROBLEM TO BE SOLVED: To provide a system with which the signal of voice, cry or music can be recorded, transmitted and reproduced again by a paper medium (printed matter) such as postcard or letter. SOLUTION: On the sides of transmission and reception, a means 8 for converting a voice to a printing pattern while having a prescribed algorithm and a converting means 7 for inversely returning the printing pattern to the voice are provided, and the voice is recorded on the side of transmission, converted to print data by the prescribed algorithm and converted to a prescribed printing pattern 3 corresponding to its audio signal. Then, the printing pattern is printed on the paper medium and distributed to the side of reception. On the side of reception, the printed paper medium is read, the prescribed printing pattern is extracted, and the printing pattern is returned to the voice by the prescribed algorithm. Thus, the recorded voice on the side of transmission can be reproduced. |
