The voice of hearing-impaired individuals has been described extensively, and exhibits abnormalities in quality, articulation and resonance. Having an understanding of the aspects that may have an impact on voice characteristics of cochlear implant users is important for users and for professionals in this field.
To verify the existence of correlation between age, time of device use, voice detection threshold, hearing category score and language category score with acoustic data of voices of cochlear implanted children.
Retrospective study. Fifty-one children ranging in age from 3 years to 5 years and 11 months who unilaterally used cochlear implants participated. Acoustic analysis of the sustained vowel/a/, sequential speech and spontaneous speech was performed. The results were correlated with demographic data and hearing test results.
Children with worse voice detection threshold showed higher frequency in the sustained vowel (p≤0.001) and in the spontaneous speech (p≤0.005).
There was a correlation between the voice detection threshold and the frequency values of the sustained vowel and spontaneous speech of the studied population.
听力受损个体的嗓音已被广泛描述，其在音质、清晰度和共鸣方面存在异常。了解可能影响人工耳蜗使用者嗓音特征的因素，对使用者及该领域的专业人员而言都很重要。
验证年龄、设备使用时间、嗓音检测阈值、听力类别评分和语言类别评分与人工耳蜗植入儿童嗓音声学数据之间是否存在相关性。
回顾性研究。纳入51名单侧使用人工耳蜗、年龄在3岁至5岁11个月之间的儿童。对持续元音/a/、连贯言语和自发言语进行声学分析。将结果与人口统计学数据和听力测试结果相关联。
嗓音检测阈值较差的儿童在持续元音（p≤0.001）和自发言语（p≤0.005）中表现出更高的频率。
在所研究人群中，嗓音检测阈值与持续元音和自发言语的频率值之间存在相关性。
