Duration of the Japanese 'sokuon' and 'haneruon' in Korean and Japanese pronunciation

The aim of this paper is to measure the duration of Japanese 'sokuon' [t/k] and 'haneron' [m/n] pronounced by Korean and Japanese. It is revealed in this study that gemination of the Japanese 'sokuon' in Korean pronunciation lasts 1.5 times longer than a single consonant, whereas it lasts 2 times longer in Japanese pronunciation. The difference between Korean and Japanese seems to show the difficulty of perceiving and learning a foreign rhythmic pattern non-existent in the leaner's language. The gemination of [s] phoneme lasts 2 times as long as a single consonant in both Korean and Japanese pronunciation. On average, the duration of Japanese 'sokuon' [t/k/s] is 1.7 times longer than a single consonant in Korean pronunciation, whereas 2 times longer in Japanese pronunciation. The pronunciation of Japanese 'haneruon' by either Korean or Japanese produces a similar result: 1) gemination lasts longer than a single consonant, 2) the duration of the single [m] is longer than that of the single [n]; 3) gemination of [n] is 3 times as long as a single [n], whereas gemination of [m] is 2 times as long as a single [m].
