Examples of syllabic nasals in English abound in phonological research (e.g., Hammond, 1999; Harris, 1994; Wells, 1995), but there is little explicit discussion about the surrounding consonant environments that condition syllabic nasals. This study examines 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, a corpus of read speech with speakers from the Pacific Northwest and Northern Cities, and a spontaneous telephone speech corpus. Acoustic analysis indicates that [n] is only prevalent after [ʔ], with some extension to [d] or [ɾ]. Variation in rates of [n] versus [ən] is found across the speakers in a group, not within individual speakers. An articulatory sketch to account for the prevalence of [n] after coronal and glottal stops is laid out. To link this realization to the presence of the [ʔ] allophone in pre-syllabic nasal environment, previous analyses of acoustic enhancement proposed for glottally-reinforced [tʔ] in coda position (e.g., Keyser & Stevens, 2006) are extended to the syllabic nasal case.

美式英语中音节鼻音和声门塞音之间的联系

音节鼻音在英语中的例子比比皆是（例如，Hammond, 1999; Harris, 1994; Wells, 1995），但很少明确讨论影响音节鼻音的周围辅音环境。这项研究检查了美式英语中潜在的词尾音节鼻音的产生，这些音节鼻音在前面的辅音包括口塞音、声门塞音、擦音、拍打和侧音之后。这些数据来自对来自纽约和其他地区的演讲者的朗读语音的实验室研究、来自太平洋西北地区和北部城市的朗读演讲的语料库以及自发的电话语音语料库。声学分析表明，[n] 仅在 [ʔ] 之后流行，对 [d] 或 [ɾ] 有一些扩展。[n] 与 [ən] 的比率在一组中的说话者中存在差异，不在个别发言者之内。一个发音示意图解释了冠状和声门停止后 [n] 的普遍性。为了将这种认识与前音节鼻音环境中 [ʔ] 同位异音的存在联系起来，先前对声门增强 [tʔ] 在结尾位置提出的声学增强分析（例如，Keyser & Stevens，2006）扩展到音节鼻腔病例。
