ABSTRACT
English exhibits compensatory shortening, whereby a stressed syllable followed by an unstressed syllable is measured to be shorter than the same stressed syllable alone. This anticipatory shortening is much greater than backward shortening, whereby an unstressed syllable is measured to shorten a following stressed syllable. We speculated that measured shortening reflects not true shortening, but coarticulatory hiding. Hence, we asked whether listeners are sensitive to parts of stressed syllables hidden by following or preceding unstressed syllables. In two experiments (Experiments 1A and 1B), we found the point of subjective equality-that is, the durational difference between a stressed syllable in isolation and one followed by an unstressed syllable-at which listeners cannot tell which is longer. In a third experiment (Experiment 2), we found the point of subjective equality for stressed monosyllables and disyllables with a weak-strong stress pattern. In all of the experiments, the points of subjective equality occurred when stressed syllables in disyllables were measured to be shorter than those in monosyllables, as if the listeners heard the coarticulatory onset or the continuation of a stressed syllable within unstressed syllables.
