| 主权项 | 1. A signal processing method comprising: calculating a correlation coefficient indicating a degree of relation between a left stereo signal and a right stereo signal of a stereo signal, the calculating comprising calculating a first coefficient indicating a first degree of relation between the left stereo signal and the right stereo signal based on a past first coefficient indicating the first degree of relation between the left stereo signal and the right stereo signal in a past frame; and extracting a speech signal from the stereo signal by using the correlation coefficient and the stereo signal. | ||
