The purpose of this study was to examine how a singing program using self-voice monitoring for children with cochlear implants (CI) influences on the intonation and the accuracy of pitch production. To verify and estimate the effectiveness, a program was conducted with participants of 7 prelingual CI users, whose aged between 4 years and 7 years. The program adopted three stages from the self-voice monitoring: Listen, Explore, and Reproduce (LER stage). All participants received 8 singing sessions over 8 weeks, including pre-test, intervention, and post-test. For the pre and post-test, participants' singing of an excerpt of a song "happy birthday" and speaking three assertive sentences and three interrogative sentences were recorded and analyzed in terms of the intonation slopes at the end of the sentences and the melodic contour. From the sentence speeches, we found that the intonation slopes of the interrogative sentences significantly improved as they showed similar patterns with that of the average normal hearing group. Also, in regard to singing, we observed that the melody contour had progressed, as well as the range of pitch production had extended. The positive result from the intervention indicates that the singing program was effective for children with CI to develop the intonation skill and accuracy of pitch production.
