Abstract

Background and Aim: Speech is known as the most important auditory signal that humans deal with it. Noise can mask speech and prevent spoken information from reaching us. Researchers have been trying to develop indexes to assess speech intelligibility. Speech Intelligibility Index (SII) is one of these indicators and we intend to introduce its nature and applications. Recent Findings: SII is a method that numerically demonstrates the ability to hear speech in difficult listening situations. The number 1.0 indicates that all spoken information is available, while 0.0 indicates that the person does not have access to any information. Hearing loss changes a person’s scores on this index, so we need to use corrective factors to more accurately estimate speech intelligibility. In children, the SII score is different from adults. This indicator can be used in the improvement of hearing aid fitting and more accurate adjustment of cochlear implants. The frequency importance function used to calculate SII has a unique shape in each language. Therefore, SII will also differ in different languages, depending on the nature of each language. Conclusion: SII has emerged as a practical indicator among objective assessments of speech intelligibility. Many have tried to extend and prepare it for use in different groups. Therefore, care should be taken about the use of this index in hearing-impaired people, children, with hearing aids or cochlear implant patients, etc. Evaluation of this index in other languages can help to better adjust the hearing aid based on the characteristics of each language.   Keywords: Speech intelligibility index; hearing loss; children; hearing aid; cochlear implant; language
语音清晰度指数:文献回顾
背景与目的:语言被认为是人类处理的最重要的听觉信号。噪音可以掩盖说话,阻止说话的信息传达给我们。研究人员一直在尝试开发评估语音清晰度的指标。语音清晰度指数(SII)就是其中的一种指标,本文将介绍其性质和应用。最近的发现:SII是一种用数字来证明在听力困难的情况下听到说话的能力的方法。数字1.0表示所有所说的信息都是可用的,而0.0表示该人没有访问任何信息的权限。听力损失会改变一个人在这个指标上的得分,所以我们需要使用校正因子来更准确地估计语音可理解性。儿童的SII得分与成人不同。该指标可用于改善助听器的配合度和更准确地调整人工耳蜗。用于计算SII的频率重要性函数在每种语言中都具有独特的形状。因此,SII在不同的语言中也会有所不同,这取决于每种语言的性质。结论:SII已成为客观评估语音可理解性的实用指标。许多人试图扩展和准备它以供不同群体使用。因此,对听障人士、儿童、配戴助听器或人工耳蜗患者等使用该指标时应谨慎。在其他语言中对该指标进行评价,有助于更好地根据每种语言的特点对助听器进行调整。关键词:语音清晰度指标;听力损失;孩子;助听器;人工耳蜗植入;语言
