The invention provides a sound control communication processing method, an earphone, a storage medium and a computer, which are applied to first communication equipment, and the method comprises the following steps: autonomously receiving an external environment sound signal; performing separation processing on the external environment sound signal to obtain a voice signal and a noise signal; performing segmentation processing on the voice signal to obtain a plurality of voice signal segments, and performing windowing and framing processing on each voice signal segment; calculating an average amplitude value of the voice signal segments after windowing and framing processing, and judging whether the average amplitude value is greater than or equal to a preset voice control threshold value or not; if yes, the voice signal is sent to a second communication device, and the second communication device communicates with the first communication device through a local area network. The technical ...
