The speech analysis system allows for an undisturbed speech generation by the person. The system first writes out the test sentence, clears it and shows afterwards a sequence of visual clues to the person in order to remind him of the correct wording. The person is reminded of the sentence and repeats it exactly but without any influence through letters. The method provides visual clues that remind the person of the exact sentence, without influencing his pronunciation.
