Speaking Clearly for the Hard of Hearing IV: Further Studies of the Role of Speaking Rate Export

@article{citeulike:4876309, abstract = {The contribution of reduced speaking rate to the intelligibility of "clear" speech (Picheny, Durlach, \& Braida, 1985) was evaluated by adjusting the durations of speech segments (a) via nonuniform signal time-scaling, (b) by deleting and inserting pauses, and (c) by eliciting materials from a professional speaker at a wide range of speaking rates.
