The invention provides a voice signal processing method and device, relates to the field of signal processing technologies and earphones, and is used for providing full-band and low-noise voice signals. The method is applied to the earphone comprising at least two voice collectors, the at least two voice collectors comprise an ear canal voice collector and at least one external voice collector, and the method comprises the following steps: preprocessing a voice signal in a first frequency band collected by the ear canal voice collector to obtain a first voice signal; voice signals in a second frequency band collected by the at least one external voice collector are preprocessed, external voice signals are obtained, and the frequency range of the first frequency band is different from that of the second frequency band; correlation processing is performed on the first voice signal and the external voice signal to obtain a second voice signal; and a target voice signal is output, wherein the target voice signal
