| Abstract(in English) | This paper reports comparative evaluations of the method we previously proposed of estimating fundamental frequency (F_0) based on complex cepstrum analysis with nine typical methods over huge speech-sound datasets in both artificial and realistic reverberant environments (in room coustics). They involve several classic algorithms (Cepstrum, AMDF, LPC, and modified autocorrelation) and a few modern algorithms (TEMPO, YIN, and PHIA). The comparative results revealed that the percentage correct rates of the estimated F_0s using them were drastically reduced as the reverberation time increased while F_0 estimated with the proposed method was completely robust and accurate. They also demonstrated that homomorphic analysis and the concept of a source-filter model were relatively effective for estimating F_0. The results also demonstrated that it was much better than the previously reported methods in terms of robustness and providing accurate F_0 estimates in both artificial and realistic reverberant environments. |
