Replication data for: Northern Sangtam phonetics, phonology and word list (Dataset AC4-20110704_NSA1)

This dataset (AC4-20110704_NSA1) contains transcribed word lists and accompanying sound files in Northern Sangtam (ISO 639–3: nsa), an Aoic language spoken in central Nagaland, Northeast India. The word list is based on the elicited data of a 66-year-old native speaker and constitutes the replication data for Coupe, Alexander R. (2020) Northern Sangtam phonetics, phonology and word list, Linguistics of the Tibeto-Burman Area 43:1, pp. 148–189. This paper presents a comprehensive phonetic and phonological description of this hitherto undocumented language. Special attention is given to two of the world’s rarest phonemes discovered in the consonant phoneme inventory: a pre-stopped bilabial trill, and a doubly-articulated labial-coronal nasal. The paper presents a systematic description of the syllable and word structure, the tone system, and the segmental phonology, concluding with a discussion of some observed age-related differences in the phoneme inventory.
