Posh accent and vocal attractiveness in British English

Abstract

Posh accent in British English is associated with upper class. Previous research on poshness has been centred on vocabulary, grammar and phonology, but little is known about the phonetic properties. This study, as part of a larger project, is an attempt to connect posh accent with attractiveness of voice through a common set of dimensions originating from emotional prosody research. Using VocalTractLab and Praat, we created stimuli varying in voice quality, nasality, formant shift ratio, pitch shift and duration. Results of two separate perception experiments showed that only voice quality and formant shift ratio functioned significantly. Breathy voice sounded the most posh and attractive, and pressed voice the least. Likewise, utterances with the smallest formant shift ratio sounded the most posh and attractive.
