This paper proposes a new method of recognizing the four tones, the method is based on the functional model for the process of generating F0 contours of sentences, so our method is different from proposed others, it is applied to the four tone recognition not only for monosyllables, but also for disyllables, phrases and even sentences. This method is adaptable to every speaker with a simple training procedure using only "MA" four tones. It can recognize the lexical tones using a few parameters. The recognition accuracy is over 99% for monosyllables, 93% for disyllables and idioms of four-syllable.
