This paper reports statistics on the fundamental frequency distribution in 145 dysphonic voices and 5 normal subjects with special emphasis on the occurence of low frequency component in connected speech. We used kernel density estimates with Epanechnikov kernel and optimal bandwidth for mode detection. Density estimates of the F0-distribution for 150 voices showed in 48% of cases a bimodal distribution, which was understood to be due to a notable amount of creaky voice and subharmonic frequencies. The distribution characteristics of F0 in dysphonic voices have been used to investigate their effect on roughness judgements. We demonstrate the limitations of describing dysphonic voices in terms of mean, median and frequency range values in long-term F0 measurements and suggest that modal analysis would offer an additional dimension in describing dysphonic voices.
