摘要: This study investigates whether patterns of diachronic sound change within a language variety can predict phonetic variability useful for distinguishing speakers. An analysis Standard Southern British English (SSBE) monophthongs is undertaken to test individuals differ more widely in their realisation sounds undergoing than stable sounds. The vowels /ae, ʊ, uː/, demonstrated by previous research be changing SSBE, are compared with the relatively /iː, ɑː, ɔː/. Read speech 50 male speakers SSBE aged 18-25 from DyViS database analysed and earlier results 20 First, data confirm stability ɔː/, fact that /ʊ, uː/ have indeed fronted articulation /ae/ has become open. Results discriminant based on F1 F2 frequencies show speaker classification rates well above chance. non-stable all achieved higher levels discrimination /ɔː/. However, highly variable pronunciation some case few ‘special’ status /ɑː/ /iː/, increasing rate those vowels, made overall picture complicated.
