“…Bergvall 1999 briefly discusses how popular interpretations of sex-based behavioral differences are explained in terms of physical differences. Certainly, the difference between men's and women's vocal fold length would account for the almost uniform finding that the average pitch in adult men is lower than in women (Weaver 1924, Snidecor 1951, Linke 1973, Coleman 1976, Lass, Hughes et al 1976, Loveday 1981, Günzburger 1984, Gilmore et al 1992. But if differences in pitch are purely physiological, this could not account for the better-than-chance ability to distinguish between the voices of preadolescent boys and girls, whose physical articulatory properties and average pitch are similar (Weinberg & Zlatin 1970, Weinberg & Bennett 1971, Sachs, Lieberman & Erickson 1973, Bennett & Weinberg 1979a, 1979b, Bresser & Günzburger 1985, Günzburger, Bresser & ter Keurs 1987, Lee, Hewlett & Nairn 1995.…”
