Tracking of Speech Formant Frequencies
İbrahim Yücel Özbek, Mübeccel Demırekler · 2006
This study is about tracking of formant frequencies using Kalman filtering. Assuming that the formant frequencies are changing in time slowly, it is possible to model their behaviors as outputs of a dynamic system and then track them using Kalman filtering approach. Tracking system considers also the orders and possible intervals of each formant frequency.
