This paper reports on a collaborative cross- linguistic study which compares lateralised productions of /s/ in Japanese and British English. EPG recordings were made of four Japanese and three British patients. The EPG patterns were classified according to certain criteria , such as the presence/absence of complete constriction, and the area and location of the contact. It was found that, although lateralised productions varied between the speakers, Japanese and English productions were broadly similar. Acoustically, productions in both languages were characterised by a lower frequency of peak energy than would be expected in a normal speaker's productions. The implications of this work for the assessment of this type of speech disorder are discussed.
