Abstract  Abstract

A first pitch information extracting step of extracting first pitch information from a frame using frequency domain analysis, a second pitch information extracting step of extracting first pitch information from a frame using frequency domain analysis, A pitch candidate providing step of providing a pitch candidate from the first pitch information, the at least one pitch candidate being associated with a spectral score and representing a possible pitch estimation value for the frame; and a second pitch information extracting step of extracting second pitch information from the frame using time- A step of extracting pitch information from the first pitch information, a step of extracting pitch information from the second pitch information, a correlation score providing step of providing a correlation score for at least one pitch candidate from the second pitch information, A pitch extraction method, system and related com A computer readable medium is disclosed. The method, system and associated computer readable medium are suitable for speech coding and distributed speech recognition.
