The influence of non-contrastive phonetic details such as intergestural
timing, stop release burst and articulatory effort expense on phonological
patterning has been discussed extensively in Browman & Goldstein
(1992), Flemming (1995), Jun (1995), Kirchner (1997), Silverman (1997),
Boersma (1998), Gordon (1999), Hayes (1999), Steriade (1999, 2000),
Zhang (forthcoming), among others. Even though the way in which
phonology incorporates phonetic factors is debatable (see Hayes &
Steriade, forthcoming for an overview of the debate and § 3.1.1 for more
detailed discussion), the fact that there exist phonological patterns that are
governed by phonetic factors seems less so. In this paper, without
committing myself to any view of how phonetic factors are encoded in
phonology, I present the case of Chinese retroflex suffixation in support of
the relevance of non-contrastive phonetic features to categorical phonological
patterning. In addition, I argue that MAXFEATURE constraints
(Lombardi 1995, 1998, Casali 1996, Pulleyblank 1996, Causley 1997,
Walker 1999; henceforth Max[F]) are needed to account for the data in
question.
