This particular pronunciation of /t/, in which the /t/ receives an s-like secondary articulation, has received little scholarly attention to date. B&P conclude that this variant of /t/ can be regarded as fortition, in the sense that this pronunciation makes the /t/ more prevalent in strong positions in the syllable. The main element of this thesis is an empirical study based on the study carried out by Buizza and Plug (2012). It consists of a small-scale reproduction of their research in which I analyse spontaneous speech using the speech-analysis programme Praat (Boersma & Weenink 2017). The goal of this thesis was twofold: (i) to see whether I obtained similar results as B&P and (ii) to extend our knowledge on this variant of the RP English /t/, which could in turn deepen our understanding on developments of the RP English /t/. In doing so, I help investigate how the distinction between fortition and lenition can be researched. I conclude that my results partly reflect the results in B&P, although the distribution of [ts] over the positions considered is slightly different. This can in part be explained by the smaller scale and by the choices that I made during the categorization of the data. I also add that, in researching sound changes such as fortition and lenition, it might be worth looking at the influence of surrounding words.Show less
