Rosetta Stone software displays images, and includes audio clips of native speakers. Rosetta Stone uses very few tools for learning languages, but the few tools it does use are perfected. This includes easy to hear and understand language clips. Pronunciation of words and phrases is coherent, unlike some audio CD courses. Rosetta Stone language software provides feedback on the progress of the student, and allows the student to toggle between any of the lessons the student wants to focus on. The added flexibility of the program, combined with a progress tracking system that gives the student feedback, gives the student greater power to manage the learning experience. The amount of control the student has over the learning interface allows the student to improve in areas where the student needs more practice.
