environment, deriving a number <strong>of</strong> distinct phenomena found there from this general<br />

tendency (i.e. final devoicing, stress retraction, vowel loss) 84 . This conclusion is seriously<br />

at odds with the findings catalogued above.<br />

For consonants, previous work suggests a solution to this contradiction. Certainly<br />

the study <strong>of</strong> Keating, Wright and Zhang (1999) shows a marked strengthening effect for<br />

consonants in phrase-final position in English, such that their linguopalatal contact<br />

becomes in some cases equal to that <strong>of</strong> comparable word-initial consonants in the same<br />

phrasal position 85 , a pattern standing in direct opposition to the idea <strong>of</strong> phrase-final<br />

articulatory weakness. On the other hand, Steriade (1997) analyzes the tendency for a<br />

variety <strong>of</strong> consonantal contrasts to be neutralized in word-final position (and elsewhere)<br />

as stemming from a lack <strong>of</strong> robust cues to consonant identity in that environment.<br />

Specifically, lack <strong>of</strong> CV transitions and release burst obscures cues to consonant place<br />

and laryngeal specification. We may add to this the sharp amplitude drop extremely<br />

common if not universal in most phrase- or utterance-final syllables, and along with that<br />

the tendency to phrase-final voicelessness cited by Hock, and what emerges is a picture<br />

<strong>of</strong> the extreme perceptual weakness <strong>of</strong> consonants in final position, despite whatever<br />

84 An important aspect <strong>of</strong> Hock’s conclusions, though, is on the need to distinguish phrase-final (in his<br />

terms “Finality”) effects from word-final (“Right Edge”), in that in phrase-final position there is <strong>of</strong>ten<br />

phonetic motivation for weakening (e.g. for final devoicing, see below), while in word-final but phraseinternal<br />

position that motivation may be lacking. This means that weakening processes common to both<br />

environments almost certainly begin in the larger domain and are generalized to the smaller. This parallels<br />

what we have seen for final lengthening above.<br />

85 Results are for the consonants /t, d, n, l/. The effect was weaker for /l/ than for the other consonants.<br />
