DIGITAL technologies are the new life-savers for languages on the verge of extinction, linguists said Friday as they announced eight new dictionaries at a major science conference in Vancouver.

"We're turning the digital divide into a digital opportunity," said David Harrison, a National Geographic Fellow at Swarthmore College near Philadelphia.

More than half of some 7,000 languages alive today were considered on the verge of extinction within a century, "threatened by cultural changes, ethnic shame, government repression and other factors," the scientists said in a paper.

But use of technologies, even by peoples without written languages, "is a heartening trend," said Harrison. "Language extinction is not an inevitability."

"Using social media, Youtube, text messaging, to expand their voice, expand their presence (is) the flip side of globalisation," said Harrison.

"You can have a language spoken by only 50 or 500 people, only in one location, and now through digital technology that language can achieve a global voice."

Linguist Margaret Noori said languages are a gateway to so-called traditional knowledge. For example, an Ojibwe term for wetlands, translated as "where the land bleeds,' shows a different way of understanding the science of a place," she told reporters.

Noori said that in North America's Great Lakes region, apps for iPhones, a Facebook page, online lessons and a web site with dictionaries and songs are keeping alive the aboriginal Anishinaabemowin language.

Noori said new estimates show just 5,000 people in North America speak Anishinaabemowin, once the mother tongue of 200 aboriginal nations, known as tribes or bands.

"I told my daughter 'you can't have an iPhone unless you text me in the App'," Noori quipped.

Harrison released eight new "talking" dictionaries of languages at the American Association for the Advancement of Science meeting in Vancouver.

The dictionaries include Matukar Panau, an Oceanic language spoken by just 600 people in Papua New Guinea; Chamacoco, spoken by some 1,200 people in northern Paraguay; the Indian languages Remo, Sora and Ho; and Tuvan, used by nomads in Siberia and Mongolia; and a Celtic-tongue dictionary.

The talking dictionaries are produced by National Geographic's Enduring Voices project and the Living Tongues Institute for Endangered Languages.
