"In normal conversation we speak at a rate of about 300 syllables a minute. To do this we force air up through the larynx . . . and, by variously pursing our lips and flapping our tongue around in our mouth rather in the manner of a freshly landed fish, we shape each passing puff of air into a series of loosely differentiated plosives, fricatives, gutturals, and other minor atmospheric disturbances. These emerge as a more or less continuous blur of sound. . . . Syllables, words, sentences run together like a watercolor left in the rain. To understand what anyone is saying to us we must separate these noises into words and words into sentences so that we might in our turn issue a stream of mixed sounds in response . . . . And yet we achieve the process effortlessly." Bill Bryson, The Mother Tongue (Avon 1990) p. 90.
Enough said.
