Abstract
In the description of nasality in normal, typical speech the range of different types of nasal segments is relatively small. In the speech of individuals with atypical oronasal structure and/or function there is a much greater range of types of nasality. This note amplifies and extends the categories of atypical nasality described in Duckworth, Allen, Hardcastle and Ball (1990 Clinical Linguistics & Phonetics, 4, 273–283).
