Quantitative Evaluation in children with articulation disorders -About Effect of using a I-SCAN system-

儿童的发音与身体功能和发音器的发育有关。声学分析是评估和治疗各种类型的发音障碍，特别是唇腭裂患者的畸变音的有效方法。研究对象由健康儿童和唇腭裂儿童组成。（都有完整的初级牙列）。测试音是基于元音[a]在辅音[s]和[∫]之前和之后，就像在VCV音节[asa]和[a∫a]。VCV音节中的辅音部分由记录声学数据中的声谱指定，并采用通用估计方法的倒频谱平滑对数谱对可视化频谱包络中声压最高部分的频率值进行了调查。然而，唇腭裂的孩子无法发出这些声音，因为他们没有正常的牙弓和嘴唇，所以这些孩子会产生补偿性语言模式。在治疗唇腭裂患儿时，不仅需要进行正畸治疗和手术，还必须考虑言语治疗。

The articulation of children occurs in association with the development of physical functioning and the articulator. Acoustic analysis is a useful method to assess articulation and treat various types of articulation disorders, especially distorted sounds of the cleft-lip and palate patient. The subjects were composed of healthy children and children with cleft lip and cleft palate. (all with complete primary dentition). The test sounds were based on the vowels [a] preceding and following the consonants [s] and [∫] as in VCV syllable [asa] and [a∫a]. The consonant part in the VCV syllable was specified by the sound spectrum in recorded acoustic data, and the investigation of the frequency values of parts that showed the highest sound pressure of a visualized spectrum envelope were conducted using the cepstrum smoothing logarithmic spectrum of a universal estimation method.However, children with cleft lip and palate are unable to produce these sounds, since they do not have a normal dental arch and lip, so these children produce compensatory speech patterns.There is a need for not only orthodontic treatment and surgery, but also speech therapy must be considered when treating the cleft lip and palate child.
