It is well-attested that the coronal stops are frequent sounds in English and produced with various phonetic realizations in spontaneous speech. This study analyzes phonological variations of coronal stops such as glottaling, flapping, deletion depending on phonetic, phonological and sociolinguistic factors. The data examined in this study are taken from the Buckeye Corpus of Conversational Speech. Based on the spontaneous American English speech it specifically focuses on coronal stop variations of a sequence of word-final post-vocalic /t/ and /d/ and the following word-initial consonants across a word boundary. Results of this study indicate that the rate of glottaling was most prevalent for coronal stop variations such as glottaling, flapping and deletion. Word frequency, voicing of coronal stop and sonorant of following consonant played an important role to the coronal stop variations. Coronal stop variations across the word boundary were involved in various types of consonantal lenition processes where coronal stops lose their place feature and become weaker to achieve ease or economy of articulation.
