Nasal Coarticulation and Prosody in Kakataibo

This paper presents the first phonetic description of the patterns of nasal coarticulation in Kakataibo. While closely related Panoan languages have been described as having anticipatory nasal coarticulation in VN sequences, there are only a few reports of other types of nasal coarticulation. Based on a detailed investigation of the aerodynamic properties of nasality, we account for the full variety of nasal coarticulation patterns in Kakataibo and discuss their interaction with prosody. This paper shows that nasal coarticulation occurs in all contexts in which there is vowel-nasal contiguity, although the amount and patterns of nasal coarticulation are dependent on the directionality of the process, the presence or absence of a syllable boundary and stress.
