| Abstract(in English) | A new excitation source information analysis method, called XSX (eXcitation Structure extractor) has been investigated to analyze voices with complex excitation behavior; such as singing voices, pathological voices, emotional voices and so on. This article illustrates advantages of XSX over existing PDAs (pitch determination algorithms) and introduces prospective applications. A comparative study with YIN and SWIPE, two well know PDAs, using a harmonic multiple sinusoids with a common frequency modulated fundamental component was conducted and revealed that XSX has superior response to the modulation frequency. Detailed analyses using XSX were also conducted for pathological voices, which displayed large discrepancies between results by XSX and other PDAs. The analyses by XSX clearly indicated that subharmonics by coupling multiple basic periods are sometimes more prominent than the usual fundamental components. These results and advantages illustrates that XSX is useful for analyses of voices with complex behavior, which makes analyses by existing PDAs impractical. |
