A Study for the Development of Korean Articulation Map as a Speech Therapy Guideline for Children with CLP

This study aims to find visual parameters of Korean articulation map to develop speech therapy guidelines for children with CLP. Understanding the anatomical mechanism of Korean alphabet, Hangeul, production is probably the basic step to provide appropriate speech intervention for anybody in need. The Korean consonant consists of relatively high percentage of plosives which need high oral pressure and the manner of voiceless plosive sounds are differentiated by three according to their features called, ‘tense,’ ‘aspirated.’ These features make it difficult to perceive or produce for people who have problems with hearing and/or orofacial structure like cleft palate. As a basic step to develop an articulation place map for Hangeul, this study searched journals on speech perception to find the visual parameters which contribute the most to perceive speech sounds. The extracted visual parameters are as follows: A change of musculature tension and length, movements of orofacial structure, a shape of vocal tract, aerodynamic interactions, and acoustical features released.
