title: Incoordination of the phonation start in individuals with balbuties.
abstract: We studied the effect occurring in close proximity before the phonation start and give an account of the microdramas taking place upon the glottis immediately before the phonation start in a group of individuals suffering from balbuties (60 children and adolescents from 9 to 14 years of age) and an equally large control group suffering from no such speech defect. In the group of children and adolescents with balbuties only less than 4% of the cases showed undisturbed regular phonation starts, whereas in the control group it was almost as much as 90%.
