Problems solved by technology

[0003] In the existing earphone echo cancellation scheme, the echo cancellation is performed through the call noise reduction algorithm. This method has very high requirements for the sealing of the call microphone, but due to various reasons, the seal of the call microphone is not good, so the call The echo problem is serious during the process

Abstract

The invention provides an echo cancellation method, a device, computer equipment and a storage medium, which are applied to an earphone. The earphone comprises a loudspeaker and a first microphone forcommunication, and the earphone further comprises a second microphone which is arranged in a front cavity of the earphone and is close to the loudspeaker. The echo cancellation method comprises the following steps of: acquiring first sound information acquired by a first microphone, and acquiring second sound information acquired by a second microphone; performing content comparison on the firstsound information and the second sound information; and if the first sound information has target sound information with the same content as the second sound information, removing the target sound information from the first sound information. Echo information in the first sound information is eliminated through content comparison, and echo interference is avoided.

Description

technical field [0001] The present application relates to the technical field of earphones, and in particular to an echo cancellation method, device, computer equipment and storage medium. Background technique [0002] When the user wears a headset to talk, the headset microphone will collect what the user said and send it to the intercom terminal through the network. Part of the sound signal is received by the user's ear, and part is received by the microphone of the user's earphone, and is transmitted to the intercom end via the network, so that the intercom end can hear its own echo. [0003] In the existing earphone echo cancellation scheme, the echo cancellation is performed through the call noise reduction algorithm. This method has very high requirements for the sealing of the call microphone, but due to various reasons, the seal of the call microphone is not good, so the call The echo problem is serious during the process. Contents of the invention [0004] The m...
