Tapped /r/ in RP: a corpus-based sociophonetic study across the twentieth century

Abstract

Abstract This paper aims to explore the use of the tap allophone [ɾ] in Received Pronunciation (RP) in word-internal and linking /r/ contexts over three decades (1940s–1960s) and considering three age cohorts (<35 years old, 35–54 years old, and ≥55 years old). A spoken corpus of formal register materials was compiled to conduct further perceptual and acoustic analysis and classify the articulation of /r/ into tap versus no tap. Results show a decreasing tendency of tap production across decades, and the initial stage of its replacement by the approximant variant. From a sociolinguistic perspective, tapped /r/ may have potentially changed its status, from an indicator to a marker. The fact that the tap allophone has become a sociolinguistic marker can encourage future research on intra-speaker variation. Women and middle-aged speakers (35–54 years old) are the ones leading this sound change, opting for the innovative approximant. This may be due to professional pressures or aspects of social identity, yet further research is needed. Furthermore, the word-internal context seems to favour the production of taps, which could be due to the general low frequency of linking /r/ and the formal register of the materials.
