“…In English , phonetic observation has revealed that the closure for the first consonant in a cluster generally is not released until after the closure for the second is formed (e . g ., Kenyon , 1951 ;Jones , 1956 ;Abercrombie , 1967 ;Catford , 1977 ;MacKay , 1978 ;Hardcastle & Roach , 1979 ;see Henderson & Repp , 1982 on acoustic consequences) . Barry (1985) , Nolan (1992) , Browman & Goldstein (1990b) , and others have shown that an initial consonant in a cluster that may sound as if it has been assimilated in place of articulation , or deleted altogether , is often in fact still articulated at its original point of articulation .…”
