### Short Summaries of Articles about Mathematics

in the Popular Press

"Speaking of Mathematics," by Brian Hayes. *American Scientist*, March-April 1996, pages 110-113.

"Profile: T. V. Raman. Envisioning Speech," by W. Wayt Gibbs. *Scientific American*, September 1996, pages 52-54.

These two articles discuss the challenge of building computer devices that convert text to speech when the text contains mathematical expressions. T. V. Raman, a blind mathematician and computer scientist who now works for Adobe Systems, formulated such a device in his doctoral dissertation in 1994. He has constructed a high-level programming language that controls the way mathematical expressions are spoken by a computer voice synthesizer.
