Medieval aragonese is still spoken in the valley and in a few other parts of the Aragón Pyrenees. It is also reviving in the towns and cities of the region. Hecho is one of the valleys where the language is best conserved and the dialect here is called Cheso. As well as listening to the locals speak there are is plenty of written work in Cheso from authors such as Veremundo Méndez, Domingo Miral and Rosario Ustáriz. You can also read articles in Cheso in the valley magazine, Bisas de lo Subordán.
