The purpose of this study is to clarify the phonological variation of word-final /nt/ sequences in English, considering the first segment of the following words. This study collects data from the Buckeye Corpus of Conversational Speech (Pitt et al. 2007) and analyzes the distribution of the variation using the Observed/Expected frequency analysis method. Subsequently, the distribution is formalized employing the maximum entropy grammar (Hayes and Wilson 2008). This approach provides a robust explanatory framework for predicting the tendency of different phonological outcomes, such as /t/-deletion, glottalization, and flapping. As a result, the /t/-deletion of the word-final /nt/ sequences is most likely to occur before obstruents, while glottalization is most likely to occur before sonorant consonants and pauses. Flapping is predominantly observed before vowels and is notably rare in front of other types of variables.
