Problems solved by technology

[0008] Since the prior art restores the voice signal by decoding a single voice stream, two voice signals will be generated and output separately during such a call, so that only the voice call records of one party to the call can be recorded separately, and there is a lack of a technology Means to process the voice call records of both parties in the call as a whole output, which reduces the quality of service

Embodiment Construction

[0028] Embodiments of the present invention provide a voice stream processing method and a voice stream processing device, which can realize the combined processing of at least two voice streams, thereby realizing the simultaneous monitoring of two-party calls or even multi-party calls.

[0029] Before describing the embodiment of the present invention, we can briefly explain the VoIP implementation principle in the prior art as follows.

[0030] VoIP realizes the separation of call control and data transmission. The call control protocol ensures the smooth implementation of telephone calls and voice quality. Currently, the widely accepted VoIP control signaling system includes the International Telecommunication Union Telecommunication Standardization Sector (ITU- T) H.323 series and the Session Initiation Protocol (Session Initiation Protocol, SIP) of the Internet Engineering Task Force (Internet Engineering Task Force, IETF). The data transmission technology mainly adopts t...

Abstract

The invention discloses a voice stream processing method, including the acquirement of two voice streams at least. The time sequences of voice data packets in the voice streams are adjusted and the voice compressed frames of the adjusted voice streams corresponding to the voice data packets are outputted synchronously, then the compressed voice frames which are synchronously outputted are restored into original voice frames. In the end, the original voice frames of the voice streams corresponding to the same time are merged. The invention also discloses a voice stream processing device. By the invention, the two voice steams at least can be processed by merging, thereby realizing the monitor of a dialogue between two parties and even among a plurality of parties, and enhancing the service quality.

Description

technical field [0001] The invention relates to the field of voice communication, in particular to a voice stream processing method and a voice stream processing device. Background technique [0002] At present, Voice over Internet Protocol (VoIP) technology based on Internet Protocol has gradually moved from experiment to commercial use. The environment of the IP) network carries out the transmission of voice signals, which is commonly referred to as Internet telephony, Internet telephony or IP telephony. [0003] However, in the actual application of VoIP, we have encountered many practical problems, such as security, which is a key problem that needs to be solved urgently in the development of VoIP, and it is also an obstacle to the further development of softswitch technology in the softswitch environment. It can be predicted that the high-speed development period of multimedia communication has come, but to promote this business to the public, we must pay attention to ...
