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

儿童的发音与身体机能和发音器的发展有关。声学分析是一种有效的方法来评估和治疗各种类型的发音障碍，特别是唇腭裂患者的失真的声音。研究对象包括健康儿童和唇腭裂儿童。(all完整的乳牙列）。测试音基于辅音[s]和[]之前和之后的元音[a]，如VCV音节[asa]和[a a]。VCV音节中的辅音部分由记录的声学数据中的声谱来指定，并且使用通用估计方法的倒谱平滑对数谱来调查显示可视化的谱包络的最高声压的部分的频率值。然而，唇腭裂儿童不能发出这些声音，由于他们没有正常的牙弓和嘴唇，所以这些孩子会产生代偿性的语言模式，在治疗唇腭裂儿童时，不仅需要正畸治疗和手术，而且还必须考虑语言治疗。

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.
