Abstract(in English) | A new implementation of STRAIGHT spectral estimation based on so-called TANDEM windowing was applied to investigate statistical properties of vowel spectral variations in POP-song singing. The implementation enabled analysis of real world data as a whole. STRAIGHT spectra of singing voice were converted into MFCC filter outputs and MFCC parameters prior to statistical analyses. Principal component analysis of MFCC converted whole data including vowels, consonants and pauses indicated that more than 90.0% of total variation was resided within the first 5 principal components. It was also found that the space spanned by eigenvectors and that by the MFCC basis functions have similar structure. Relatively large overlap of intra-class distance distributions and interclass distance distributions was observed indicating larger spectral variations of singing voice caused by wider range of variability in pitch, loudness, effort and other timbre related attributes. Implications of these results on adopting a vowel based speech conversion method to singing voice conversion are also discussed. |
