Examination of an articulation assessment method that uses acoustic analysis

受试者包括42名发育正常的儿童，5名被言语-语言-听力治疗师诊断为由于舌系带过短而导致的构音障碍的儿童，以及5名来我院就诊的唇腭裂儿童，所有受试者的最大频率峰值<s>和<sh>发音的比较显示，39名受试者的发音峰值<s>高于发音峰值<sh>。舌系带过短和唇腭裂患儿的最大频率峰值有低于正常儿童的趋势，且正常儿童的最大频率峰值差异较大。这可能是因为儿童需要时间来完善辅音的发音，特别是需要在舌尖进行熟练运动活动的发音，导致发音的高度波动。

Subjects comprised 42 unimpaired children with no discernible problems in development , 5 children diagnosed with dysarthria due to ankyloglossia by a speech-language-hearing therapist, and 5 children who visited our hospital with cleft lip and palate.Comparison of the maximum frequency peaks of <s> and <sh> articulations for all subjects revealed that the peak for <s> articulation was higher than that for <sh> articulation in 39 subjects. Frequencies of tended to be lower in children with ankyloglossia or cleft lip and palate than those in unimpaired children In addition, maximum frequency peak varied greatly among unimpaired children. This may be because it takes time for children to perfect the articulation of consonants, particularly articulations that require skilled motor activity in the lingual apex, resulting in high volatility of articulation.
