Lingual contact to palate was observed utilizing electro‐palatography in the utterances of Japanese monosyllables, words and sentences by fifteen adult subjects (nine males and six females). Based on the palatograms recorded with sixty‐four electrodes at every 20 msec and the measurements of the three‐dimensional shape of the plaster cast of the subjects' palates, personal characteristics of the lingual articulations of Japanese vowels and consonants and their coarticulatory effects were analyzed. Changes in the characteristics of lingual articulations of children caused by the growth of their palates were also observed, and the points to be considered for making the artificial palates in the application of the electro‐palatography to the speech training of hearing‐impaired children were discussed as well.
