Variability in (r) production: instrumental perspectives

The As. investigate the variability in /r/ production from an instrumental perspective. They provide an overview of the acoustic and articulatory properties of /r/, with particular reference to anterior approximant variants. Second, they exemplify some of these properties by describing an acoustic study of variation in /r/ production by speakers of British English from Newcastle and Derby, drawing attention in particular to the labiodental approximant [υ], a variant of /r/ which is gaining currency in these and other varieties of English but which is not typically included within the class of rhotic sounds
