For certain types of speech coding algorithms, it is important to determine accurately the pitch period or the fundamental frequency of the speech signals. A new fundamental frequency determination method based on the instantaneous frequency estimation is presented in this paper. A bank of two bandpass filters is used to eliminate and attenuate the harmonics of the speech signals. The fundamental frequency can be determined from the estimated instantaneous frequencies of the filtered speech signals. This new method can be used to obtain a continuous fundamental frequency as a function of time. Also, it does not seem to have the problem of occasional incorrect frequency estimation, such as frequency doubling or halving. |
