1. Three cases of dysarthria syllabaris spasmodica are presented. Each case had difficulty only in articulating syllables beginning with the consonant k in the Japanese alphabet. Two of these cases, both boys aged 7 years, were quickly cured of their speech disorder. The remaining case, a 16-years-old boy, was cured after 5 weeks of treatment.
2. On the evidence of sonagrams taken during the course of treatment in a 16-years-old boy and observation of the position of the tongue, there appeared to be a site most suitable for articulation of the consonant k for distinct enunciation of the k-syllables.
