Primate Vocalizations and Human Linguistic Ability

摘要: Some representative vocalizations of captive rhesus monkey, chimpanzee, and gorilla were recorded analyzed by means sound spectrograms oscillograms. It was found that these animals' vocal mechanisms do not appear capable producing human speech. The laryngeal output breathy irregular. A uniform cross section, schwalike configuration appeared to underlie all the vocalizations. These animals did modify shape their supralaryngeal tracts tongue maneuvers during a vocalization. Formant transitions occurred in some vocalizations, but they have been generated possibly velar or lip movements. nonhuman primates lack pharyngeal region like man's, where cross‐sectional area continually changes data suggest speech cannot be viewed as an overlaid function makes use tract has evolved solely for respiratory deglutitious purposes; skeletal evidence evolution shows...
