Re: effects of replay on intelligibility
Here is one lead that used synthetic speech...
"repeated listening experiences resulted in significantly improved
scores for both novel and repeated vocabulary [...] repeated
vocabulary was more intelligible than novel vocabulary. The results
provide evidence that repeated listening experiences result in
improved performance for both children and adults. Children and adults
not only remember and recognize words that they have heard previously
(repeated vocabulary), but repeated exposure to synthesized speech
also improves performance on words heard for the first time (novel
