Abstract	The purpose of this letter is to explore some reasons for what appear to be conflicting reports of the nature and extent of anticipatory coarticulation (Kozhevnikov and Chistovich, 1966; Lubker and Gay, 1982, Bell-Berti and Harris, 1982; Engstrand, 1981; Perkell, 1986; sussman and Westbury, 1981). Generally, these results have been claimed to support one of two conflicting positions: One view, which we will refer to as the look-ahead model (e.g. Henke, 1976) is that articulatory features of a target phone migrate to preceding phones to an extent that depends on the feature composition of the latter. Another view, which we will refer to as frame theory (Bell-Berti Harris, 1982), presumes that anticipatory coarticulation is due to the coproduction of neighboring segments (Fowler, 1980) in a relatively temporal frame. It is our position that (1) the apparent conflicts depend in substantial part on assumptions made about the feature specification of phones, and (2) experimental design can obviate the need for such assumptions. In particular, we will refer to anticipatory lip rounding, although we believe that we are addressing the general phenomena of anticipatory coarticulation (Bladon and Al-Bamerni, 1982).
