The use of cochlear implant results in the optimization of speech perception, and, as a consequence in the development of oral language, speech and voice of its users, demonstrating to be one of the most effective and promising technologies to remedy hearing loss. However, little has been studied about the relationship between auditory skills and the voice of children using cochlear implants.
To relate the speech perception abilities to the vocal characteristics of cochlear implant users.
Perceptive and acoustic analysis of the long vowel /a/ and counting of numbers were carried out. This analysis was compared to a standardized speech perception protocol, that evaluates the recognition of words, its phonemes and consonants.
It was observed that the higher the recognition of consonants, the higher the maximum frequency, standard deviation of the fundamental frequency and average of intensity during the sequential speech, as well as fundamental frequency average during the emission of the vowel /a/. Also, the higher the recognition of consonants, the lower the standard deviation of the quality of voice and resonance in the perceptive-auditory analysis.
Among the children with cochlear implants, the ones with better speech perception abilities present lower perceptive-auditory deviations of the quality of voice.
人工耳蜗的使用可优化言语感知，进而促进使用者的口语发展、言语和嗓音，证明是治疗听力损失最有效且最具前景的技术之一。然而，关于人工耳蜗使用者的听觉技能与嗓音之间的关系，研究甚少。
将人工耳蜗使用者的言语感知能力与嗓音特征联系起来。
对长元音/a/进行感知和声学分析以及数字计数。该分析与评估单词、音素和辅音识别的标准化言语感知方案进行比较。
观察到辅音识别率越高，连续言语期间的最高频率、基频标准差和强度平均值以及元音/a/发声期间的基频平均值越高。此外，辅音识别率越高，在感知-听觉分析中嗓音质量和共振的标准差越低。
在人工耳蜗使用者中，言语感知能力较好的儿童在嗓音质量的感知-听觉偏差方面较低。
