Vowel errors in children‘s articulation have often observed in children with low intelligibility of articulation, deafness or cerebral palsy. As Vowels have generally been neglected in the past literature, consequently, procedures for assessment and treatment of vowel are extremely limited. On the other hands, investigations of vowel errors in children have been primarily limited to English speaking children. The present paper provided some methodical consideration of vowel analysis of production at korean children with articulation disorders and those of normal language development. Focused on the error of vowel /u/, was investigated with two methods of vowel analysis, which is articulatory phonetical 'process analysis' and acoustic phonetical 'formant anaysis'. According to the result of present data, acoustic analysis with first and second formant confirmed the validity of perceptual based analysis of vowel processes, such as lowering and fronting. In addition, for the analysis of accurate place of articulation of vowel or general tendency of vowel articulation is useful to analysis of formant frequency of vowel.
