Purpose: Hearing children can talk by recognizing the speech of another speaker. Hearing impaired children can develop correct articulation through having a cochlear implant. Previous studies looked at various background factors to speech recognition ability for cochlear implanted (CI) people, including chronological age, age at cochlear implantation, hearing period with CI, and language age. The purpose of this study was to find the background factors affecting articulation production when CI people speak. Methods: Forty-nine CI people who have had speech processor cochlear implants for at least one year and who are without other problems such as mental disorders or autisum participated in the study. To collect the speech samples, U-Tap and receptive language ability tests were used. All data was subjected to one-way ANOVA and multiple regression analysis. Results: The results show that correct articulation on CI people was about 80% and was affected by the background factors of hearing periods and language age. That is, when hearing periods were longer, correct articulation increased. Language age showed the same results as hearing period. At chronological age, correct articulation scores of 4-7 year-old children were higher than children older than seven. When age at CI operation was lower, correct articulation scores were higher. However, the most influential background factor to articulation production was language age and hearing period with CI. Conclusions: People with cochlear implants improved their articulation production, but showed little improvement above the age of seven. These findings could be due to the limited acoustic range of cochlear implants and lack of auditory nerves in hearing impaired people. Among background factors of CI people, hearing age with CI and language age play important roles in articulation production.
