Abstract

The present application provides a voice synchronization method, device, system and related equipment, based on the transmitter sending a voice superframe every preset time, and the voice superframe includes a target type voice frame and multiple non-target type voice frames , the speech frame of the target type contains a synchronization word, and at least one speech frame in a plurality of speech frames of the non-target type contains a link control signaling LC, the method is applied to a receiver, and the method includes: in the slave transmission channel Find whether there is a part identical to the synchronous word in the speech frame received above; if it exists, then based on the part identical to the synchronous word, extract the speech frame from the speech frame received on the transmission channel; Find whether there is a part identical to the LC in the speech frame received on the channel; if it exists, extract the speech frame from the speech frame received on the transmission channel based on the part identical to the LC. In this application, the reliability of voice synchronization can be improved through the above methods.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a voice synchronization method, device and system, and related equipment. Background technique [0002] In the call service of DMR (Digital Mobile Radio, digital trunking communication) system or PDT (Police Digital Trunking, police digital trunking) system, the sender needs to package the voice data into voice frames, and then send a voice frame every preset time. . In order to achieve reliable communication with the sender, the receiver needs to perform voice frame synchronization. [0003] However, how to perform reliable speech frame synchronization becomes a problem. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the embodiments of the present application provide a voice synchronization method, device and system, and related equipment, so as to achieve the purpose of improving the reliability of voice synchroniza...
