Voice asks to show the letter on the screen. If the letter is selected correctly, the following is set. The order may be random or linear. Each letter is given two attempts. After the second attempt, the letter is skipped. When the letters end, a window with test results is entered (how many letters were guessed the first time, how many from the second and how many were not guessed).Pronunciation can be chosen: sounds or letters (such as "ne" or "en").
