About 2,500 languages are in danger of becoming extinct according to Unesco, and some of them are spoken by only 30 people. By the turn of the century, it is estimated that at least 50 per cent of the world’s current spoken languages will be extinct. Unesco uses a set of five categories to define how endangered a language is:

Vulnerable, where most children speak the language, but it may be restricted to certain domains such as the home;

Definitely endangered, where children no longer learn the language as a ''mother tongue'' in the home;

Severely endangered is when a language is spoken by grandparents and older generations, and while the parent generation may understand it, they do not speak it to children or among themselves;

Critically endangered is when the youngest speakers are grandparents and older, and they speak the language partially and infrequently;

Extinct - there are no speakers left.

To highlight these beautiful languages, 25 native speakers have recorded themselves saying the sentence: "A different language is a different vision of life". You can listen to all 25 below.

Wiradjuri Australia – 30 speakers left

Sadly, only 40 of Australia's original 250 indigenous languages remain. Wiradjuri is one of them, spoken in the south-western part of New South Wales. The publication of a Wiradjuri dictionary has led to a revival, with the language being taught in schools in a growing number of areas.

Aymara Bolivia, Chile, Peru – 2,000,000 speakers left

This is one of the very few Native American languages that has more than one million speakers.

Balti India, Pakistan – Unknown number of speakers left

Basque Spain, France – 660,000 speakers left

Linguistically unrelated to any known living language in the world, Basque is classed as a language isolate.

Speakers can be found in the Basque Autonomous Region, the Spanish province of Navarre, and in the department of Pyrénées-Atlantiques in France.

Belarusian Belarus, Latvia, Lithuania, Poland, Russia, Ukraine – 4,000,000 speakers left
