Speech Recognition Algorithms Improve

Many of today's speech-recognition devices rely on a formula called the Good-Turing estimator, developed by I.J. Good and Alan Turing during World War II. The formula was very successful, contributing to the breaking of the Enigma cipher, thus shortening the war. However, the Good-Turing formula doesn't always work well, and is poorly understood.

Scientists at the University of California, San Diego have created a new formula that improves upon Good-Turing and may lead to better quality speech recognition.

Perhaps we will get to Asimov's automatic transcription machine sooner than we think. See the entry for the transcriber from Isaac Asimov's 1953 novel Second Foundation.

Alternatively, you could try it the other way round; see the talking pamphlet from Harlan Ellison's 1974 story do-it-yourself for text that reads itself to you.
