Fourth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2005)
A generalized variogram is used to track vocal dysperiodicities in connected speech, which are summarized by means of a signal-to-dysperiodicity marker. To evaluate the variogram-based analysis, signal-to-dysperiodicity estimates are correlated with scores obtained by means of perceptual ratings of the degree of hoarseness, which are based on comparative judgments of pairs of speech samples. The corpora comprise four French sentences as well as vowels [a] produced by 22 male and female normophonic and dysphonic speakers.
