Abstract: | This study involved respirometric measurements of six normals and six stutterers throughout vocal and whispered readings of 12 CVC words. In each condition, dependent variables were peak air flow rates on initial and final consonants, flow duration and flow volume between peaks. The stutterers, both individually and as a group, were almost completely fluent during the readings in both conditions. At the same time, their air flow, duration and volume scores either equalled or exceeded those of the controls. These results are discussed in terms of how air flow and durational features of articulation contribute to fluent speech. Directions for future work are also described. |
