Today, researches for singing by computer have attracted attention. VOCALOID is an application to realize that aim. By inputing lyrics and melody, users can make songs sung by the computer. In order to make the singing voice more “ human ”, users must control frequency curve very carefully. Comparing with inputing lyrics or melody, this controlling presents heavy overhead for users. In this research, we propose a system for easily optimizing frequency curves with Interactive Evolutionary Computation (IEC). We compared various frequency model by evaluating the convergence performance of GA to fit one of the frequency curve of real human singing, and found a suitable one for achieving our goal. And we made a questionnaire to compare previous interface and our IEC interface. From the result of this questionnaire, we found our IEC interface can optimize frequency curve more easily than previous interface.
