Abstract
The results of dynamic measurements of carbon dioxide (CO<sub>2</sub>, in %) in exhaled air during speech are presented. Fourteen stuttering persons and 14 persons with fluent speech took part in a test that involved independent speaking and echo-assisted speaking (delayed auditory feedback). A statistical comparative analysis of average levels of CO<sub>2</sub> concentration registered during speech and resting respiration immediately before speaking indicated significant differences in non-fluent speech and insignificant differences in fluent speech. It was determined that the average concentration of CO<sub>2</sub> in exhaled air while stuttering was 1/5 lower than the concentration of CO<sub>2</sub> registered during fluent speaking.
