Bone conduction signal compensation method and device

The invention discloses a bone conduction signal compensation method and device. The method comprises the following steps of: acquiring a bone conduction signal and an air conduction signal corresponding to target voice; determining a transfer function according to the bone conduction signal and the air conduction signal, the transfer function being used for compensating the bone conduction signal; determining voice frequency points and non-voice frequency points based on the bone conduction signal, the voice frequency points being frequency points with voice energy larger than a first energy threshold, and the non-voice frequency points being frequency points with voice energy smaller than or equal to the first energy threshold; performing inter-frame smoothing processing on the amplitude-frequency response of the transfer function corresponding to the voice frequency points and the non-voice frequency points to obtain a first amplitude-frequency response; in each psychoacoustic scale band, calculating a sec
