The aims of this study was to investigate influences of speech discrimination score(SDS) depending on inter-syllable pause duration in participant with child of cochlear implantation(CI). 12 child of CI-user participated. The word for SDS was used self-made meaningless three-syllable. The pause duration of inter-syllable was adjusted to 250, 500, 1,000 millisecond(ms). Discrimination score of closed-set speech was obtained at most comfortable loudness(MCL). SDS were improved in CI group for 62.08, 63.75, 69.58 %, but there were no significant changes in child of CI group(p = .4635). SDS was improved depending on inter-syllable pause duration in child of CI.

Speech discrimination is affected by the speed of speech. The speed of speech can be adjusted at the pause duration, the pause duration can take the resting time to avoid in overloading information. The study will be examine the effects of aging and audiological rehabilitation, and the auditory processing as basic research to investigate the normative data. 7 boys and 8 girls were participated. They have no problem with speech language pathologically and audiologically. There are 4 sets of test implement, and each test set was made out with 20 3-syllable words. Pause duration of all of these words are adjusted in normal(250 ms), slow(500 ms) and very slow(1000 ms). There are 4 words for a multiple-choice that including one word with written correctly and three words with written 1 phoneme wrong. Participant hear the word, and then have to choose one. Speech discrimination score in 250, 500, 1,000 ms of pause duration were $73{\pm}19.4%$, $84{\pm}12.2%$, $88{\pm}8.8%$, respectively.
