Abstract
Japanese strings with a certain duration of vowels and plosives are perceived as strings with geminated plosives. To some extent, the same is true with English strings. What differs between Japanese strings and English strings and what exactly controls the gemination perception of English strings are not yet clear. Arai & Kawagoe (1996) showed that syllable types affect the perception ratio of English strings. This paper reports the perception ratios obtained from a test using three pseudo English strings as stimuli with constant vocalic and plosive duration. The results show some significant differences among the three syllable types. And also, unlike Japanese strings, pseudo English strings with longer vocalic duration do not need longer plosive duration to be perceived as geminate.
