Navigating through either the PP1 or the PP2 application is extremely simple, with intuitive menu systems directing the user through lessons and exercises, although tutorial and help menus are available, most users will probably not need to reference them. Exercises - that are not available in PP2, as well as, a variety of interactive games that provide opportunities for listening and speech production practice. The Lessons area of study offers visual and auditory instructions for producing each sound. For the side view, animated drawings provide an x-rayed look of the complete articulatory mechanics, including manner and location of airflow, lips and tongue placement and movement, velum movement, and whether a sound is voiced or voiceless. For the front view, a video clip of a real person is shown, demonstrating jaw, lip, and tongue protrusion movement.
