At the novice level the picture will be uncovered easier; the expert level is the most difficult one. By reading the text aloud into the microphone, the user trains his or her intonation. A vertical line coming in from the right from a picture covered by black squares is used to show the extent to which the user is successful. If the line turns green, this indicates that speech contains a high level of intonation and as a consequence, the picture is revealed. If the vertical line turns red, this indicates that speech is monotonous and the picture is covered up. The absolute percentage of the user`s intonation level is shown at the right. If the user passes this session successfully (the picture is completely revealed), he or she is able to enter a more difficult level.
