Abstract

Although substantial variability is observed in the articulatory implementation of the constriction gestures involved in/ɹ/production, studies of articulatory-acoustic relations in/ɹ/have largely ignored the potential for subtle variation in the implementation of these gestures to affect salient acoustic dimensions. This study examines how variation in the articulation of American English/ɹ/influences the relative sensitivity of the third formant to variation in palatal, pharyngeal, and labial constriction degree. Simultaneously recorded articulatory and acoustic data from six speakers in the USC-TIMIT corpus was analyzed to determine how variation in the implementation of each constriction across tokens of/ɹ/relates to variation in third formant values. Results show that third formant values are differentially affected by constriction degree for the different constrictions used to produce/ɹ/. Additionally, interspeaker variation is …
