Acoustic Loci and Transitional Cues for Consonants

Abstract
Previous research with simplified, synthetic speech has shown that formant transitions, i.e., relatively rapid shifts in frequency, can be cues for the aural identification of various consonant phones and, further, that the same transition will apparently serve for consonants that have the same articulatory place of production. The data of the present series of experiments permit a tentative specification of certain frequency-positions, or “loci,” which appear to be characteristic of consonants according to their place of production, and toward which the transitions of the vowel formants point. Taking account of these loci provides a basis for an economical description of many of the data concerning the role of transitions in consonant identification.
