Dear Linda, You may be interested in the clear / conversational speech literature - "clear speech" is hyperarticulate speech directed toward listeners with hearing lossand there has been research on perception of clear speech by the following; Ann Bradlow Sarah Hargus Ferguson and Diane Kewley-Port Picheny, Durlach, and Braida I hope I have those last names right. I'm sure there are others that I am forgetting right now, but that's a start!

Offhand, we couldn't think of any evidence that this is true. There are papers on times when people use hyperarticulation (speaking to children, correcting misperceptions, etc), but nothing on how easy the speech is to understand if someone hyperarticulates all the time. Does anyone have answers or evidence? Thanks. Linda Shockey School of Languages and European Studies University of Reading Whiteknights, RG6 6AA 0118 - 378-7469
