INCOORDINATION OF THE PHONATION START IN INDIVIDUALS WITH BALBUTIES

We studied the effect occurring in close proximity before the phonatio n start and give an account of the microdramas taking place upon the g lottis immediately before the phonation start in a group of individual s suffering from balbuties (60 children and adolescents from 9 to 14 y ears of age) and an equally large control group suffering from no such speech defect. In the group of children and adolescents with balbutie s only less than 4% of the cases showed undisturbed regular phonation starts, whereas in the control group it was almost as much as 90%.
