The application points out which sounds learners are struggling with and offers them directions on how to improve. Elsa is able to evaluate and give specific scores to learners based on their ability to imitate a native speaker.

In addition to the technical development, the program had the support of speech coach and actor Paul Meier, who provided the voice for the app. 

SXSWedu, funded by the Bill and Melinda Gates Foundation, is one of the world's leading competitions for start-up projects specializing in education. 

Elsa's creators received a $2,500 prize for their win.
