This study suggested speech generation device(SGD) program to materialize the proper communication aids which address to language abilities by students with cerebral palsy in the stage of word recognition achievement. This SGD program aim at function of learning mediation and communication expression by synchronization not restrict aim of AAC aids' employment to the only function of communication expression. And this SGD was designed to evaluate language abilities of student with cerebral palsy through analysis of the date offered at this program, and then might utilize to set learning goals and objects, modify teaching contents. This SGD program have a meaning on contribution to possible teaching the user AAC aids, students with cerebral palsy by whole language approach in natural environment but in artificial situation at script.

The aim of this study is to prepare basic data that can be used for evaluation and intervention by investigating the characteristics of diphthongs produced by children with speech sound disorders. To confirm this, two groups of 10 children each, with and without speech sound disorders were asked to imitate the meaningless two-syllable 'diphthongs + da'. The slope of F1 and F2, amount of change of formant, and duration of glide were analyzed by Praat (version 6.1.16). As a result, the difference between the two groups was found in the slope of F1 of /ju/. Children with speech sound disorders had smaller changes in formants and shorter duration time values compared to normal children, and there were statistically significant differences. The amount of change in formant in the glide was found in F1 of /ju, jɛ/, F2 of /jɑ, jɛ/, and there were significant differences in the duration of glide in /ju, jɛ/. The results of this study showed that the range of articulation of diphthongs in children with speech sound disorders is relatively smaller than that of normal children, thus the time it takes to articulate was reduced. These results suggest that the range of articulation and acoustic analysis should be further investigated for evaluation and intervention regarding diphthongs of children with speech sound disorders.
