対話型遺伝的アルゴリズムを用いた多様なサイン音生成手法の提案

抄録

Sign sounds are used in various daily situations. However, they are not made by reflecting user's own preference. This study proposed Interactive Genetic Algorithm (IGA) method creating various sign sounds suited with each user's preference and objective. The proposed method created sign sounds by using all musical notes, while a previous IGA method have created different sign sounds by using musical rules for restriction of use of musical notes. To investigate the efficacy of the proposed method, two listening experiments were performed with a concrete system based on the proposed method. Result of the listening experiments creating bright and warn sign sounds showed significant increases of fitness value.
