A sequence of a coronal nasal and a voiceless coronal stop is subject to many phonological variations such as deletion of the nasal, deletion of the stop or deletion of the nasal and subsequent flapping of the stop. This paper analyzed the 184 sequences of a coronal nasal and a voiceless coronal stop appeared in the Buckeye Corpus of Conversational Speech to explore aspects of the variations. Results showed that the percentage of stop deletion prevailed with 80.43% while no change and flapping rates marked as low as 17.93% and 1.63%, respectively. Such a pattern reveals the effect of exposure frequency and applies as one of the most sensitive parameters in phonological alternations. Frequency in use of the words was also related and proportional to the stop deletion, which shows that cross-linguistically unmarked [coronal] and coronal stops are deleted as the word frequency increases. Gender and age factors, however, were unrelated to the patterns of variations.
