ACOUSTIC CORRELATES AND PERCEPTUAL CUES IN SPEECH - OPEN PEER COMMENTARY

Locus equations are supposed to capture a perceptual invariant of plac e of articulation in consonants. Synthetic speech data show that human classification deviates systematically from the predictions of locus equations. The few studies that have contrasted predictions from compe ting theories yield mixed results, indicating that no current theory a dequately characterizes the perceptual mapping from sound to phonetic symbol.
