| Abstract(in English) | Vocal parameters (e.g. pitch, intensity, timber) are randomly fluctuating and systematically changing at the same time while singing. A series of analyses were conducted to reveal this intensity related systematic change in timbre using RWC music database and newly recorded singing sounds. The newly recorded sounds consisted of crescendo and decrescendo singing where intensities are systematically changing. They also consisted of sounds with constant intensity. A male adult with singing experience was participated in the recording. The STRAIGHT spectra of these samples were converted to third octave band levels. Then, they were converted to orthogonal components using the principal component analysis. Regression analysis of the principal components and the sound pressure levels revealed that the eigenvector of the first principal component closely represents the systematic spectral variation due to change in intensity. A preliminary test indicated that introducing spectral modifications based on this observation improves naturalness of synthesized crescendo and decrescendo singing. |
