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.

“Spig Wead: Ive been thinking what a heel Ive been about you and about my own kids. I dont know, when I do something, I go all the way. Living. Gambling. Flying. I tap myself out. I guess thats the way I want it to be. Maybe even the way I am.
Minne Wead: Star-spangled Spig. Damn the martinis, full speed ahead and dont give up the ship.”

“The hearing ear is always found close to the speaking tongue; and no genius can long or often utter anything which is not invited and gladly entertained by men around him.”
—Ralph Waldo Emerson (18031882)
“The future of America may or may not bring forth a black President, a woman President, a Jewish President, but it most certainly always will have a suburban President. A President whose senses have been defined by the suburbs, where lakes and public baths mutate into back yards and freeways, where walking means driving, where talking means telephoning, where watching means TV, and where living means real, imitation life.”
—Arthur Kroker (b. 1945)
