This study investigates the effect of a speech recognition task on acoustic measures of voice quality. Type of speech recogntion (discrete and continuous) and vocal load of a speaker receive particular attention. A rise in F0, a common finding in voice fatigue studies, appears as the most consistent finding. It is interpreted as part of hyperfunctional mechanism countering early signs of voice fatigue.
