“…Some of these studies have shown that the duration of the speech segment preceding the target segment affects the perception of the target [English stop voicing, Summerfield, 1981;Port and Dalby, 1982;Kidd, 1989; Italian stop length, Pickett et al, 1999]. Other studies have shown that the duration of speech segment following the target segment affects the target perception [e.g., [ba/wa], Miller and Liberman, 1979;Dutch vowel length, Noteboom and Doodeman, 1980;[tʃa/ʃa], Newman and Sawusch, 1996;[ba/wa], [aba/apa], Diehl and Walsh, 1989;Diehl et al, 1991Diehl et al, , 2004. The current study adds to the first body of research showing the forward direction of normalization is at work for the perception of Japanese stop length.…”
