PROBLEM TO BE SOLVED: To simply and inexpensively actualize a so-called stealth dot pattern which can not be visually identified on a medium surface, and to actualize correspondence of the dot pattern to voice data and reproduction of the voice data. SOLUTION: An input and reproduction method of the voice data includes a step which inputs voice through a microphone, a step which photographs the medium surface printing the dot pattern through a camera set in a mobile telephone terminal, a step which generates related information by corresponding a dot code number obtained from a photographed image of the dot pattern to the voice data, a step which stores the dot code number, the voice data and the related information in a storage means, and a step which retrieves the related information of the storage means on the basis of the dot code number obtained from the photographed image, reads the voice data associated with the related information out of the storage means and reproduces it if the dot pattern of the medium surface is photographed by the camera of the mobile telephone terminal.
