Abstract  Abstract

The invention discloses a kind of disposal route of voice data, device and system, belong to communication technical field.Described method comprises: the noise frame obtaining sound signal, and described current noise frame is decomposed into noise lower-band signal and noise highband signal; With noise lower-band signal described in the first discontinuous transmission mechanism coding transmission; With noise highband signal described in the second discontinuous transmission mechanism coding transmission.The present invention is by the processing mode different with lower-band signal to highband signal, can save computation complexity and coded-bit under the prerequisite not reducing codec subjective quality, the bit under saving can reach and reduce transmission bandwidth or the object for improving binary encoding quality.
