This paper describes a robust two-phase pitch marking method based on peak-valley decision and dynamic programming. In the first phase, we select either peaks or valleys for pitch mark candidates according to its similarity to an estimated pitch curve. In the second phase, we define state and transition probabilities, and then employ dynamic programming to find the most likely pitch marks. We have also designed different tests to demonstrate the feasibility of the proposed approach.
