Neltume helps blind people to memorize and exercise words and phrases in a foreign language through a multiple selection system.

The whole system is based in an Audio Interface manipulated through buttons, so the person doesn't need to see the device in order to use it.

A bast majority of the blind population in Third World countries are living in poverty conditions and are unemployed, that means that this device needs to be as cheap as possible.

In the first iteration of the project the whole system is in Spanish, intended for blind people who want to learn English.
