Abstract: Aspects of the disclosure provide a responding method and device, an electronic device and a storage medium. The method is applied to a first electronic device including an audio acquisition component and an audio output component. The method can include acquiring a voice signal through the audio acquisition component, determining whether to respond to the voice signal, and responsive to determining to respond to the voice signal, outputting a first sound signal by the audio output component, the first sound signal being configured to notify at least one second electronic device that the first electronic device responds to the voice signal. In such a manner, an electronic device, responsive to determining to respond to a voice signal, outputs a sound signal to prevent other electronic device(s) from responding to the voice signal, so that competitions between electronic devices are reduced and a user experience is improved.

Abstract: A whistling sound suppression method includes: obtaining an ambient audio signal, the ambient audio signal being a sound signal in a surrounding environment of an earphone; filtering the ambient audio signal according to a preset first filter group to obtain a first audio signal; obtaining an ear canal audio signal, the ear canal audio signal being a sound signal when the first audio signal propagates in an ear canal; and filtering a subsequently obtained ambient audio signal according to a preset second filter group to obtain a second audio signal in response to the ear canal audio signal meets a whistling condition.

Abstract: A method for audio and video synchronization, includes: receiving audio data sent by the video player, wherein the audio data includes more than one audio sampling points; obtaining a network delay change between the audio player and the video player, wherein the network delay change refers to a time difference between the network delay monitored for the first time and the network delay monitored for the last time; determining a total amount of audio data to be adjusted according to the network delay change; and adding audio sampling points to the received audio data or deleting audio sampling points from the received audio data according to the total amount of audio data to be adjusted and a preset adjustment strategy, so that the audio player is synchronized with the video player, and playing the added or deleted audio data.
