In this research, we have studied the static features of three main Farsi vowels, uttered by four pre-lingual cochlear implant (CI) children. Speech samples have been studied before the CI operation and every three months, up to nine months postoperation. To assess the effects of the auditory feedback (AF) on the speech quality, patients have spoken with their CI devices in both on and off positions. Quantitative results show that 1) after nine months post-operation, almost all of the static features converge towards their normal values, and 2) the dependency of the static features on the AF decreases with time, which implies that the speech production motor patterns of the patients have been trained in time.
