In recent work, Labov (1994: Ch 6; 2010: Ch 6) discusses how low vowels do not appear to possess the property that he calls “peripherality” by default. Instead, low vowels may be better described in terms of dimensions adapted from Stampe’s (/1979) Natural Phonology framework; that is, the dimensions of vowel color known as palatality, labality, and sonority. However, Labov’s discussion of these dimensions, as well as the impact changes in those dimensions may have on low vowels in the course of sound change, is arguably fairly vague in these publications.
Given this fact, this week, I have chosen to post several important sources of information on vowel color as defined within the framework of Natural Phonology. These include Stampe’s (1972) “On the natural history of diphthongs”; Donegan’s (aka Miller–Donegan of “Donegan (1978)–On the Natural Phonology of vowels” fame, here all of her papers save one are published under the name Miller) “Some context-free processes affecting vowels” (1972a), “Vowel neutralization and vowel reduction” (1972b), “Bleaching and coloring” (1973), and “Raising and lowering” (1976); and Perkins’s (1977) “A sociolinguistic glance at the Great Vowel Shift of English.”
