an acoustic and sociolinguistic study of the TRAP/STRUT configuration
This study addresses diachronic change in the short vowel system of RP. While TRAP lowering and backing in RP has been reported previously, the movements STRUT has undergone have proven more difficult to determine. This study identifies a TRAP/STRUT 'rotation' using acoustic measurements of the short vowel space, showing variation across generations and an identifiable direction of change during the course of the 20th century.
