Embodiment Construction

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] In Internet voice intercom, echo and delay are the main factors affecting call quality. please participate figure 1 , on the A side, the human voice a is recorded through the microphone b, the speaker c plays the sound transmitted from the B end, part of the sound e played by the c is also recorded by the microphone b, and the sound e is the echo, so that the sound e and the sound a are both transmitted to the On the B side, the sound played by the speaker j includes the human voice a and the sound e, and the sound e is transmitted from the B en...

Abstract

The invention discloses a network voice synchronization and denoising communication system, comprising a receiving device and a network voice intercom device; the receiving device comprises a receiving module, an audio decoding module and an audio playing module; the network voice intercom device comprises a synchronization module, an echo cancellation module, an audio coding module and a transmitting module. The network voice synchronization and denoising communication system has the advantages that by using the system provided by the embodiment of the invention, data synchronization is performed on an audio stream recorded locally and an audio stream transmitted by an opposite terminal, and the audio stream transmitted by the opposite terminal is used as reference audio for filtering echoes, the coding and decoding are optimized and the echoes are canceled, thus the intercom call quality of network voice is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network voice synchronous noise-canceling communication system. Background technique [0002] With the continuous development of science and technology, people's requirements for life are getting higher and higher, and the connection between each other is more frequent. With the wide application of android system and 4G network, network voice calls on the android system are becoming more and more common. People can carry out normal voice intercom communication through Ethernet, and a free, convenient, clear and smooth communication system is a direction for the development of network voice communication today. At present, there are some more mature applications on the Android system, which can meet the intercom requirements, but basically they are charged, and rarely can achieve real-time, noise-free, smooth calls. The user experience is not very satisfactory, but these r...
