Abstract
An audio signal processing method including the following steps: acquiring a bone conduction audio signal collected by a bone conduction vibration pickup device; acquiring a low frequency transfer function which matches the bone conduction audio signal and a high frequency transfer function corresponding to the low frequency transfer function, wherein the low frequency transfer function and the high frequency transfer function are corresponding transfer functions between the bone conduction audio signal and an air conduction audio signal which correspond to the same voice; and performing frequency domain extension on the bone conduction audio signal on the basis of the low frequency transfer function and the high frequency transfer function, and taking the extended initial audio as output audio. The effect of improving the integrity pf a voice signal collected by a terminal device is achieved.
