| Popis: | The scaling between female and male formant frequencies tends to be highly nonuniform across vowel categories with the result that female vowels exhibit greater between-category dispersion in the F1×F2plane than male vowels. Vocal tract modeling studies strongly suggest that this greater dispersion of female vowels is partly behavioral, rather than purely anatomical, in origin. The present study tested one explanation for this behavioral difference between females and males,viz.,that without the compensatory effect of greater dispersion, the typically higher fundamental frequency (f0) of female talkers would yield reduced identifiability of vowels because of sparser harmonic sampling of spectral envelopes. The specific question addressed was whether, all else being equal, a higher f0has the assumed deleterious effect on vowel identifiability. In two experiments, the overall effect of increasing f0beyond 150 Hz was to reduce vowel labeling accuracy. Across individual vowel categories, the effect of raising f0varied. Auditory modeling suggests that this category variation is partly attributable to differing degrees to which a high f0obscured the distinctive auditory properties of each vowel category. Consistent with the spectral undersampling account, the performance decline at high f0s was reduced or eliminated when f0was time-varying rather than constant. |
