Differences that make a difference: Do locus equations result from physical principles characterizing all mammalian vocal tracts?
W. Tecumseh Fitch, MARC DAVID HAUSER · Behavioral and Brain Sciences · 1998
Sussman and colleagues provide no evidence supporting their claim that the human vocal production system is specialized to produce locus equations with high correlations and linearity. We propose the alternative null hypothesis that these features result from physical and physiological factors common to all mammalian vocal tracts and we recommend caution in assuming that human speech production mechanisms are unique.
