T-tapping

The process of t-tapping, also known as t-voicing, is an allophonic process by which a /t/ is realised as a voiced alveolar tap [ɾ]. It is mostly associated with accents such as American and Canadian English, as well as Australian and New Zealand English. However, it is a common feature of other accents of English from England, including SSBE, especially of younger generations. It occurs intervocalically in words like British [brɪɾɪʃ], getting [geɾɪŋ], and across word boundaries as in that is [ðæɾɪz], what if [wɒɾɪf]
