Abstract

Examining articulatory compensation has been important in understanding how the speech production system is organized, and how it relates to the acoustic and ultimately phonological levels. This paper offers a method that detects articulatory compensation in the acoustic signal, which is based on linear regression modeling of co-variation patterns between acoustic cues. We demonstrate the method on selected acoustic cues for spontaneously produced American English stop consonants. Compensatory patterns of cue variation were observed for voiced stops in some cue pairs, while uniform patterns of cue variation were found for stops as a function of place of articulation or position in the word. Overall, the results suggest that this method can be useful for observing articulatory strategies indirectly from acoustic data and testing hypotheses about the conditions under which articulatory compensation is most likely.
