Abstract(in English) We have proposed a method of the pitch estimation of musical instrument sounds using comb filters for transcription. But, owing to the fluctuation of song pitches, it was difficult to estimate the pitch of sung songs by the previous method which is based on comb filters connected in cascade. This paper proposes a new method of the pitch estimation using twelve comb filters connected in parallel. In this method, we estimate the pitch by knowing the outputs decreasing frequency components among twelve outputs using SVD or similarity between adjacent outputs, instead of detecting zero outputs. Using this method, we show the pitch estimation results of sung songs.
