Speed Hearing & Speed Talking
For the specific case of speech, time stretching can be performed using PSOLA.
Time stretching can be used with audio books and recorded lectures. Slowing down may improve comprehension of foreign languages .
While one might expect speeding up to reduce comprehension, Herb Friedman says that "Experiments have shown that the brain works most efficiently if the information rate through the ears--via speech--is the "average" reading rate, which is about 200-300 wpm (words per minute), yet the average rate of speech is in the neighborhood of 100-150 wpm."
Speeding up audio is seen as the equivalent of "speed reading" .
Time stretching is often used to adjust Radio commercials and the audio of Television advertisements to fit exactly into the 30 or 60 seconds available.

Famous quotes containing the words speed, hearing and/or talking:
“The greatest felony in the news business today is to be behind, or to miss a big story. So speed and quantity substitute for thoroughness and quality, for accuracy and context. The pressure to compete, the fear somebody else will make the splash first, creates a frenzied environment in which a blizzard of information is presented and serious questions may not be raised.”
—Carl Bernstein (b. 1944)
“What Congress and the popular sentiment approve is rarely defeated by reason of constitutional objections. I trust the measure will turn out well. It is a great relief to me. Defeat in this way, after a full and public hearing before this [Electoral] Commission, is not mortifying in any degree, and success will be in all respects more satisfactory.”
—Rutherford Birchard Hayes (1822–1893)
“What we men share is the experience of having been raised by women in a culture that stopped our fathers from being close enough to teach us how to be men, in a world in which men were discouraged from talking about our masculinity and questioning its roots and its mystique, in a world that glorified masculinity and gave us impossibly unachievable myths of masculine heroics, but no domestic models to teach us how to do it.”
—Frank Pittman (20th century)
