Behavior =Slow Down! Why Some Languages Sound So Fast= By [|Jeffrey Kluger] Thursday, Sept. 08, 2011  Read more: [|http://www.time.com/time/health/article/0,8599,2091477,00.html#ixzz1XrVDdzlw] Here's one of the least interesting paragraphs you've ever read: "Last night I opened the front door to let the cat out. It was such a beautiful night that I wandered down to the garden to get a breath of fresh air. Then I heard a click as the door closed behind me." O.K., it becomes a little less eye-glazing after that, with the speaker getting arrested while trying to force the door back open. Still, we ain't talking Noël Coward here. All the same, this perfectly ordinary passage and a few others like it are part of an intriguing study just published in the journal //Language// — a study that answers one of the longest-standing questions about human speech. (Read why speaking more than one language may delay Alzheimer's.) It's an almost universal truth that any language you don't understand sounds like it's being spoken at 200 m.p.h. — a storm of alien syllables almost impossible to tease apart. That, we tell ourselves, is simply because the words make no sense to us. Surely our spoken English sounds just as [|fast] to a native speaker of Urdu. And yet it's equally true that some languages seem to zip by faster than others. Spanish blows the doors off French; Japanese leaves German in the dust — or at least that's how they sound. But how could that be? The dialogue in movies translated from English to Spanish doesn't whiz by in half the original time after all, which is what it should if the same lines were being spoken at double time. Similarly, Spanish films don't take four hours to unspool when they're translated into French. Somewhere among all the languages must be a great equalizer that keeps us conveying information at the same [|rate] even if the speed limits vary from tongue to tongue. To investigate this puzzle, researchers from the Université de Lyon recruited 59 male and female volunteers who were native speakers of one of seven common languages — English, French, German, Italian, Japanese, Mandarin and Spanish — and one not so common one: Vietnamese. All of them were instructed to read 20 different texts, including the one about the house cat and the locked door, into a recorder. All of the volunteers read all 20 passages in their native languages. Any silences that lasted longer than 150 milliseconds were edited out, but the recordings were left otherwise untouched. (Read about the death of a language.) The investigators next counted all of the syllables in each of the recordings and further analyzed how much meaning was packed into each of those syllables. A [|single] -syllable word like //bliss//, for example, is rich with meaning — signifying not ordinary happiness but a particularly serene and rapturous kind. The single-syllable word //to// is less information-dense. And a single syllable like the short //i// sound, as in the word //jubilee//, has no independent meaning at all. With this raw data in hand, the investigators crunched the numbers together to arrive at two critical values for each language: the average information density for each of its syllables and the average number of syllables spoken per second in ordinary speech. Vietnamese was used as a reference language for the other seven, with its syllables (which are considered by linguists to be very information-dense) given an arbitrary [|value] of 1. For all of the other languages, the researchers discovered, the more data-dense the average syllable was, the fewer of those syllables had to be spoken per second — and thus the slower the speech. English, with a high information density of .91, was spoken at an average rate of 6.19 syllables per second. Mandarin, which topped the density list at .94, was the spoken slowpoke at 5.18 syllables per second. Spanish, with a low-density .63, ripped along at a syllable-per-second velocity of 7.82. The true speed demon of the group, however, was Japanese, which edged past Spanish at 7.84, thanks to its low density of .49. Despite those differences, at the end of, say, a minute of speech, all of the languages would have conveyed more or less identical amounts of information. "A tradeoff is operating between a syllable-based average information density and the rate of transmission of syllables," the researchers wrote. "A dense language will make use of fewer speech chunks than a sparser language for a given amount of semantic information." In other words, your ears aren't deceiving you: Spaniards really do sprint and Chinese really do stroll, but they will tell you the same story in the same span of time. None of that, of course, makes the skull-cracking business of trying to learn a new language any easier. It does, however, serve as one more reminder that beneath all of the differences that separate Tagalog from Thai, from Norwegian, from Wolof, from any one of the world's 6,800 other languages, lie some very simple, very common rules. The DNA of speech — like our actual DNA — makes us a lot closer to one another than we think.
