A socio-articulatory study of Scottish rhoticity

Abstract

Increasing attention is being paid in sociolinguistics to how fine phonetic variation is exploited by speakers to construct and index social identity (Hay and Drager 2007). To date, most sociophonetic work on consonants has made use of acoustic analysis to reveal unexpectedly subtle variation which is nonetheless socially indexical (e.g. Docherty and Foulkes 1999). However, some aspects of speech production are not readily recoverable even with a fine-grained acoustic analysis. New articulatory analysis techniques, such as ultrasound tongue imaging (UTI), allow researchers to push the boundaries further, identifying seemingly covert aspects of speech articulation which pattern with indexical factors with remarkable consistency. One such case is postvocalic /r/ variation in Central Scotland.
