PROBLEM TO BE SOLVED: To produce proper game sound corresponding to circumferential sound. SOLUTION: A detecting part 100 detects circumferential sound and an analyzing part 110 analyzes detected circumferential sound. An assisting part 140 assists the transmission of information by game sound by the transmission of information except sound, for example, visual information (picture or character information) or body feeling information, etc., based on the analyzing result of circumferential sound. The volume balance of game sound is changed based on the analyzing result of circumferential sound. For example, the volume of voice or effective sound is increased at the time of large circumferential sound. The tone of sound, the pitch and a reproduction speed which constitute game sound are changed based on the analyzing result of circumferential sound. In this case, the tone, pitch and reproduction speed corresponding to detected circumferential sound are selected from previously prepared plural kinds of tones, pitches and reproduction speeds. Besides, a voice reproduction speed is made to be slow when circumferential sound is large. |
