Kim, Myungsook 2009. /T/-glottalization of English in Korean College Students. English Language and Linguistics 28, 1-17. The term /t/-glottalization of English refers to the phenomenon in which the alveolar voiceless stop sound /t/ is pronounced as [ʔ] and thus glottalized in some special environments. The process can be found both in many local dialects of British English and American English, proving that it is a quite popular phonological process available to most English speakers. However, most Korean college students show a difficulty in recognizing its appropriate environments as well as articulating the sound properly in the pilot test conducted for this study. The pilot study also proves that students prefer /t/-flapping, the feature of American English, to /t/-glottalization, the feature of some British English dialects, when they face two alternatives in the identical environment. This paper discusses /t/-glottalization of English as one of foreign accent markers to distinguish non-native speakers of English from native ones and also as a regional accent marker to distinguish speakers of American English from those of British English.
