AbstractThis study investigated speaker sex differences in F2 Locus equations (F2 LEs) based on linearly (Hz) and tonotopically (Bark) scaled formant measurements. F2 data based on English monosyllabic words produced by thirteen women and eleven men were tonotopically scaled and F2 LEs were derived for both the linear and tonotopically scaled formant values. Although the overall sex difference in the F2 LE slope values for women and men was significant for both sets of F2 measures, the magnitude of this difference decreased for the Bark (.047) compared to the Hz (.063) scale. The individual data revealed a significant correlation between the slope values of the Hz and Bark scale [r = .974; p<.0001] suggesting a lawful relationship between the two metrics. Further probing revealed that the F2 LE data from women were affected more by the Bark conversion than the data from men.
