Cochlear implantation (CI) improves the quality of voice and speech output. However, there are various factors that may interfere with the use of CI to accede desirable voice outcomes. The primary aim of the current study was first to measure three acoustic voice outcomes in postlingual deaf adult CI users who were Persian-speaking, and then, to compare these according to surgery- and auditory-related factors. Of interest was also to determine whether these acoustic measures were influenced by surgery- and auditory-related factors.
A number of 113 postlingual deaf adults with CI were recruited. The voice samples were recorded in the same silent room to equalize the noise of the environment. The measures of interest were analyzed with the Praat software.
Our findings revealed that time duration of CI use (P ≤ 0.008), pattern of deafness onset (P ≤ 0.011), and the interaction between them (P ≤ 0.022) significantly affected all vocal parameters. This means that the quality of voice was significantly better in the participants using CI for more than 2 years than in those using CIs for less than 2 years. On the other hand, patients suffering sudden postlingual deafness for less than 2 years had the best acoustic voice parameters compared with those suffering gradual postlingual deafness for more than 2 years.
Some of the surgery- and auditory-related factors could be the reason for changes of voice parameters in postlingual deaf adult CI users.
人工耳蜗植入（CI）可改善语音质量和言语输出。然而，有多种因素可能会干扰使用CI以获得理想的语音效果。本研究的主要目的首先是测量波斯语母语的语后聋成年CI使用者的三种声学语音指标，然后根据手术和听觉相关因素对这些指标进行比较。还感兴趣的是确定这些声学指标是否受手术和听觉相关因素的影响。
招募了113名语后聋成年CI使用者。语音样本在同一安静房间录制，以均衡环境噪声。使用Praat软件分析感兴趣的指标。
我们的研究结果显示，CI使用时长（P≤0.008）、耳聋 onset模式（P≤0.011）以及它们之间的相互作用（P≤0.022）对所有嗓音参数均有显著影响。这意味着使用CI超过2年的参与者的语音质量明显优于使用CI不足2年的参与者。另一方面，与逐渐发生语后聋超过2年的患者相比，突发语后聋不足2年的患者的声学语音参数最佳。
一些手术和听觉相关因素可能是语后聋成年CI使用者嗓音参数变化的原因。
