PROBLEM TO BE SOLVED: To provide a signal processing method capable of recognizing a speech of an interaction partner even in the presence of various circumferential noise sources. SOLUTION: This signal processing method includes steps (S11, S13) of extracting a 1st specified signal including a desired signal by using a signal obtained from some of a plurality of transducers, a step (S11) of extracting a 2nd specified signal including a signal other than the desired signal by using a signal obtained from some of some of the transducer or a new transducer, and a step (S15) of detecting the 2nd specified signal being present, the 1st specified signal being emphasized (S13) when the 2nd specified signal is absent or emphasized (S19) by using the 2nd specified signal when the 2nd specified signal is present.
