Foreign language app marks Columbus Day by adding indigenous Navajo, Hawaiian languages

Columbus Day is recognized by many people as Indigenous Peoples' Day.

A foreign language app with more than 300 million users is marking Columbus Day, which is alternatively recognized as Indigenous Peoples Day, by launching classes in two native languages.

Navajo is the most popular indigenous language in North America, said Duolingo’s lead community specialist Myra Awodey, who pushed for the addition of this Native American tongue and expressed concern about the death of languages that aren't used.

“I grew up bilingual,” speaking German and English, Awodey told ABC News. “When we lose a language, we lose access to an entire history of a kind of culture.”

Rosetta Stone, another language-teaching program, also has a Navajo course as part of its endangered language series.

There are 332,129 Americans who claim Navajo ancestry, according to the 2010 U.S. Census.

Around 600 languages have disappeared in the last 100 years, and as many as 90 percent of the world’s languages could become obsolete by the end of the century, according to the United Nations Permanent Forum of Indigenous Issues.

The app developed its course in Hawaiian after it was approached by networks of schools, organizations and programs focused on education in Hawaii.

“So many people in our community cherish olelo Hawaii, but not all of them have the time or resources to take classes,” said Poki'i Seto of the Kanaeokana network that promotes the teaching of the native Hawaiian language. "The Hawaiian language movement is carrying our olelo to places we never thought it would go. And that’s how it should be.”

Duolingo's new indigenous curricula aren’t full courses like for English or Spanish or German, but are starting as a sort of boot camps to expand later.

It’s expensive for apps to develop courses for smaller languages because the classes must use recordings of real people speaking the language. Each course needs about 30,000 utterances.

In contrast, courses for more common tongues such as English, Spanish or German can use computerized voices.

As of Saturday on the Duolingo site, there were 211 active learners in the beta version learning Hawaiian and 85 active learners in beta learning Navajo. In contrast, there are 508,000 active learners of High Valyrian from Game of Thrones and 308,000 active users learning Klingon.
