15th International Congress of Phonetic Sciences (ICPhS-15)
According to phonological accounts, consonant lenition, or reduction, is realised in a variety of forms. The form that consonant lenition takes may be governed by the dialect in which it occurs. Acoustic and EPG data were used to measure the production of word-final intervocalic /t/ in AmE, AuE, and UKE for nuclear accented, unaccented, pre-accented and accented words. Results showed strong dialectical variation. AmE speakers showed the greatest acoustic changes in consonant production across the different prosodic accent conditions, and UKE speakers showed the least. Furthermore, prosodic accent had a notably different effect on consonant duration for UKE speakers than for either AuE or AmE speakers.
