Haley, Katarina L.; Jacks, Adam; Jarrett, Jordan; Ray, Taylor; Cunningham, Kevin T.; Gorno-Tempini, Maria Luisa; Henry, Maya L. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

Yavas, Mehmet; McLeod, Sharynne – Clinical Linguistics & Phonetics, 2010
Two member onset consonant clusters with /s/ as the first member (#sC onsets) behave differently from other double onset consonant clusters in English. Phonological explanations of children's consonant cluster production have been posited to predict children's speech acquisition. The aim of this study was to consider the role of the Sonority…

Stress Conflation: Evidence from Sooke.
Davis, Stuart – 1986
A comparison of the application of two current theories of stress to a particular stress pattern found in the Salish language Sooke is presented. Hammond's (1986) grid-like tree structure representation of stress is compared with Halle and Vergnaud's (1986) tree-like grid structure. Examples in the Australian language Maranungku show that, in…
