The Extent of Coarticulation of English Liquids: An Acoustic and Articulatory Study

Paula West

Phonetics Laboratory, University of Oxford, UK

This study explores the production of long-domain coarticulatory patterns associated with English /l/ and /r/ by investigating the extent and nature of differences in articulation and acoustics. A speaker of Southern British English was recorded using simultaneous EPG and EMA. Six l/r minimal word pairs were recorded in a frame sentence. Strong local coarticulatory effects were found in the vowels adjacent to the liquid. Non-local anticipatory differences in F3, lip and tongue position were found in vowels not adjacent to the liquid, with lower F3, more lip rounding and backer and higher tongue position preceding an /r/. Non-local perseverative differences proved more elusive. EPG data showed significant differences in contact patterns for consonants up to two syllables before the liquid.
