One of the best known and most controversial features of Canadian English is the vocalic feature labeled by Chambers (1973) as “Canadian Raising”, which affects the /aI/ of right and the /aU/ of lout. This feature represents a situation in which the onset of the diphthong is closer to the target of the glide before fortis consonants than before lenis consonants: for instance, ride may have [aε] and right [3I], and loud may have [ao] but lout [ʌU]. Many of the previous studies of the feature, beginning with its original description by Martin Joos (1942), who raises the question of whether the second syllable of typewriter has the raised or non-raised variant, have involved the syllabification rules that determine when the onset is raised and when it is not. Chambers (1973) demonstrates that writer normally has the raised variant and shows that the relative stress on particular syllables can prevent raising from taking place in some cases where the diphthong occurs before a voiceless consonant. Vance (1987), Paradis (1980), and Chambers (1989) also deal with this latter problem, reformulating it in terms of linear (Vance) or Kahnian (Paradis, Chambers) theories of syllable formation.
