The disclosure discloses a method and apparatus for recognizing wind noise of an earphone. The earphone includes a first microphone located outside an ear and a second microphone located inside the ear. The method includes: a first microphone signal collected by the first microphone and a second microphone signal collected by the second microphone are acquired; a first frequency domain filtered signal is obtained based on the first microphone signal and the second microphone signal; and obtaining a wind noise recognition result of the earphone based on coherence between the first microphone signal and the first frequency domain filtered signal. According to the method for recognizing wind noise of an earphone of the embodiments of the disclosure, wind noise recognition is performed by using the existing first microphone located outside the ear and the existing second microphone located in the ear, other microphones are not needed to be set additionally, the hardware cost is reduced, and the effect of the wind noise recognition is good. The method for recognizing wind noise of an earphone is applicable to different wind noise recognition scenarios.
