The acoustic analysis of the voice was performed in 5 implanted patients (2 children and 3 adults). This analysis was made twice in each patient one week before the implantation and the second time at least three months later. The examination was carried out using the KAY Electronics 4300 instruments and the MDVP program. The comparison of the results showed: decreased F0 value of phonation tone after the surgery in all patients; mean values of jitter and shimmer were increased in relation to norm before and after the surgery in adults and children; the gap between harmonic signal and noise (NHR) was within norm in 2 adults, and in 1 child with prelingual deafness significantly decreased after the surgery. The acoustic analysis of voice of cochlear implant patients, especially children, may be the objective evaluation of progress in speech and hearing rehabilitation. In the process of rehabilitation tendencies pointing out to the normalization of voice especially in patients with prelingual deafness was observed.
对5名植入人工耳蜗的患者（2名儿童和3名成人）进行了嗓音声学分析。每位患者在植入前一周进行了两次该分析，第二次至少在三个月后进行。使用KAY Electronics 4300仪器和MDVP程序进行检查。结果比较显示：所有患者术后发声音调的F0值降低；成人和儿童术前术后的抖动和闪烁平均值相对于正常水平均有所增加；2名成人的谐波信号与噪声之间的差距（NHR）在正常范围内，1名术前耳聋的儿童术后该差距显著减小。人工耳蜗植入患者，尤其是儿童的嗓音声学分析，可能是言语和听力康复进展的客观评估。在康复过程中，观察到嗓音趋于正常化的趋势，尤其是在术前耳聋的患者中。
