The link between syllabic nasals and glottal stops in American English
Examples of syllabic nasals in English abound in phonological studies (e.g., Hammond 1999, Harris 1994, Wells 1995), but there is little explicit discussion about the surrounding consonant environments that condition syllabic nasals. In this talk, we examine the production of potential word-final syllabic nasals in American English following preceding consonants including oral stops, glottal stops, fricatives, flap, and laterals. The data come from a laboratory study of read speech with speakers from New York and other regions. Acoustic analysis indicates that [n̩] is only prevalent after [ʔ], with some extension to /d/. The results suggest that /ən/ is the appropriate underlying representation for syllabic nasals, and an articulatory sketch to account for the prevalence of [n̩] after coronal stops is laid out. To provide a link between the [ʔ] allophone and syllabic nasals, previous analyses of acoustic enhancement proposed for glottally-reinforced [tʔ] in coda position (e.g. Keyser and Stevens 2006) are extended to the syllabic nasal case.
