Problems solved by technology
[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: since in the packet switching network, the voice signal is divided into a plurality of voice segments, there is no short-term correlation between these voice segments, therefore, After the receiver device performs correlation analysis, sharp noise will be generated between two adjacent voice segments, which will reduce the quality of the voice signal

The embodiment of the invention provides a voice signal processing method and a device and a communication system. In the method, a reset frame is inserted between adjacent played voice segments, the reset frame is used for resetting the decoder of a receiver equipment; the voice segments inserted in the reset frame are sent to the receiver equipment. The device comprises a processing module and a sending module, wherein, the processing module is used for inserting the reset frame between the adjacent played voice segments, the reset frame is used for resetting the decoder of the receiver equipment; the sending module is used for sending the voice segments inserted in the reset frame to the receiver equipment. For the embodiment of the invention, sharp noises can be avoided when the adjacent played voice segments are played because the reset frame is inserted between the adjacent played voice segments, , thereby the quality of the voice signal is increased.
Description
technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a voice signal processing method and device, and a communication system. Background technique [0002] With the continuous enrichment of communication services, voice services are also developing rapidly, such as ring back tones playing, voice transmission in video playing services, and so on. [0003] A packet switching network is a network based on packet switching. The so-called packet switching means dividing service data into packets of a certain length, and storing and forwarding each packet as a unit. Therefore, when voice transmission is performed on the packet-switched network, the voice signal will be divided into multiple voice segments, and the voice segments are stored and forwarded in units of these voice segments. In a packet-switched network, in order to reduce the bandwidth of speech codec, the device at the sending end of the speech sig...
