A signal processing method performs echo reduction processing on at least one of a collected sound signal of a first microphone, a collected sound signal of a second microphone, or both the collected sound signal of the first microphone and the collected sound signal of the second microphone, and calculates a correlated component between the collected sound signal of the first microphone and the collected sound signal of the second microphone, using a collected sound signal of which echo has been reduced by the an echo reduction processing.
