Discrimination of speech by nonhuman animals: Basic auditory sensitivities conducive to the perception of speech-sound categories

Kuhl, Patricia K.·1981·The Journal of the Acoustical Society of America

Abstract

Chinchillas (Chinchilla laniger) were tested in a same–different task to determine the location of greatest sensitivity along a continuum of voice-onset-time (VOT). The procedure used was an up–down staircase technique which allowed the determination of the just-noticeable-difference in VOT (Δ VOT) for VOT’s on a continuum ranging from [dα] to [tα]. Results demonstrated that the animals were most sensitive to change (i.e., produced the smallest Δ VOT values) in the region of the phonetic boundary dividing voiceless-unaspirated and voiceless-aspirated sounds, in good agreement with the boundary value previously obtained in an identification task with this same species [Kuhl and Miller, J. Acoust. Soc. Am. 63, 905 (1978)]. The results support the notion that the mammalian auditory system provided a selective pressure on the choice of acoustic cues to represent the phonetic oppositions employed by the world’s languages. The data are discussed in terms of the original definition of categorical perception and current psychoacoustic explanations of the peak in sensitivity for two-component stimuli varying in onset time.

  • Monkeys show peaks in sensitivity that coincide with the phonetic boundaries used by languages.

    “In tests of discrimination, monkeys showed peaks in sensitivity that coincided with the phonetic boundaries used by languages (20–22) (Fig. 4).”

  • Previous research demonstrated many commonalities between young infants and animals in tests of speech perception, particularly those involving categorical perception.

    “This difference is of interest in light of previous research demonstrating many commonalities between young infants and animals in tests of speech perception, particularly those involving categorical perception (Kuhl, 1981;Kuhl & Miller, 1975, 1978;Kuhl & Padden, 1982, 1983;Morse & Snowdon, 1975;Waters & Wilson, 1976).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
