"The purpose of the Spanish in Texas project is to profile Spanish as it is spoken throughout Texas today and to provide open learning tools that allow students, teachers, and the general public to explore Spanish language variation. A central goal of the project is to encourage users to view local varieties of Spanish and their speakers as important resources for learning about language and culture.

Spanish in Texas is part of the 2010-2014 program of the Center for Open Educational Resources and Language Learning (COERLL), a National Foreign Language Resource Center at the University of Texas at Austin." Source: http://spanishintexas.org/
