The major changes are to replace the c and q[u] with a k and replace the digraph hu with the single letter w. This is considered to be part of a general growth of pride in the Andean heritage of these countries. These spelling changes have not yet been made official, but today Bolivia is a multicultural country. In the La Paz, Bolivia radio is broadcast in 12 languages.
