Developments of the Research of the Formant Tracking Algorithm

The formant is the important part of the phonetic characters, and reliable formant tracking algorithm is the base to study the phonetics. Based on the development course of the phonetic formant tracking algorithm, the linear prediction coding (LPC) and the model matching method are introduced emphatically, and there own advantages and disadvantages are analyzed, and the model matching method based on the hidden dynamic model will be the development direction of the future formant tracking technology.
