Neanderthals Speak Out After 30,000 Years
A computer synthesizer models what Neanderthals sounded like.
April 17, 2008 — -- Talk about a long silence – no one has heard their voices for 30,000 years. Now the long-extinct Neanderthals are speaking up – or at least a computer synthesiser is doing so on their behalf.
Robert McCarthy, an anthropologist at Florida Atlantic University in Boca Raton has used new reconstructions of Neanderthal vocal tracts to simulate the voice. He says the ancient human's speech lacked the "quantal vowel" sounds that underlie modern speech.
Quantal vowels provide cues that help speakers with different size vocal tracts understand one another, says McCarthy, who was talking at the annual meeting of the American Association of Physical Anthropologists in Columbus, Ohio, on April 11.
"They would have spoken a bit differently. They wouldn't have been able to produce these quantal vowels that form the basis of spoken language," he says.

In the 1970s, linguist Phil Lieberman, of Brown University in Providence, Rhode Island, inferred the dimensions of the larynx of a Neanderthal based on its skull. His team concluded that Neanderthal speech did not have the subtlety of modern human speech.
Some researchers have criticised this finding, citing archaeological evidence of an oral culture and even errors in Lieberman's original vocal tract reconstruction.
Undeterred, the linguist teamed with McCarthy to simulate Neanderthal speech based on new reconstructions of three Neanderthal vocal tracts. The 50,000-year old fossils all came from France.
By modelling the sounds the Neanderthal pipes would have made, McCarthy's team engineered the sound of a Neanderthal saying "E". He plans to eventually simulate an entire Neanderthal sentence. Listen to McCarthy's simulation of a Neanderthal voice
In contrast to a modern human "E", the Neanderthal version doesn't have a quantal hallmark, which helps a listener distinguish the word "beat" from "bit," for instance. Listen to a simulation of a modern human voice
Though subtle, the linguistic difference would have limited Neanderthal speech, McCarthy says.
