In this paper, a generic pitch marks filtering algorithm (PMFA) is introduced in order to achieve reliable and smooth pitch marks from any input pitch tracking or marking algorithm. The proposed PMFA is a simple yet effective filtering process based on restricted dynamic programming, but very helpful for minimizing human intervention when creating large speech corpora. Moreover, this work introduces a novel pitch marking evaluation measure for directly comparing pitch marking algorithms with different location criteria. The experiments demonstrate that the proposed PFMA improves the results of the input state-of-the-art pitch tracking and marking algorithms dramatically.
