Excitation source structural analysis of Japanese traditional singing voices
Hideki Kawahara · The Journal of the Acoustical Society of America · 2012
New set of voice excitation source analysis methods are applied to study Japanese traditional singing voices, especially Noh. The first method, XSX (excitation Structure extractor) is capable of visualize detailed structure of subharmonic periodicity, by using multiple dedicated periodicity detectors. The second one analyzes symmetry of the fundamental component waveform, cycle by cycle. It enables to discriminate voice onset and offset details.
