Embodiment Construction

[0062] FIG. 1 is a block diagram of a network communication device 100 according to the present invention. The network communication device 100 is connected to a personal computer 108, which in turn is connected to a network. The network communication device 100 can be a physical network phone or a network communication software module of the personal computer 108 . The network communication device 100 converts a local user's voice into an audio signal and transmits the audio signal to another remote network communication device through the network. The network communication device 100 also receives a voice signal from another remote network communication device through the network, and plays the remote voice signal so that the near-end user can hear the remote voice signal. In this way, users at both ends of the network can conduct conversations through the network. In the case of a multi-party conference, multiple remote network communication devices may be in contact with...

Abstract

The invention provides an Internet communication device. The Internet communication device plays a remote audio signal received via a network and transmits an audio signal back to the remote party to complete the communication. The Internet communication device comprises a line-in speech detection module and a line-in channel control module. The line-in speech detection module detects whether the remote audio signal is speech or not to generate a remote speech detection result. The line-in channel control module then attenuates the remote audio signal if the remote speech detection result indicates that the remote audio signal is not speech, thus, all noise including non-stationary noise is removed from the remote audio signal.

Description

technical field [0001] The present invention relates to noise cancellation, and more particularly to noise cancellation of network communication devices. Background technique [0002] Due to the high cost of traditional circuit-switched telephones, VoIP technology is gradually being used to make long-distance calls or international calls. Therefore, network communication devices such as VoIP devices or Instant Messenger have become popular. Things like Skype, MSN Messenger, Yahoo Messenger, Google Talker, AOL Messenger are all software applications for Internet communication. With the frequent use of network communication devices, the requirements for call voice quality of network communication devices are also increasing. Noise control is the key to improving the call sound quality of network communication devices. [0003] Network communication devices often need to be connected to the network via a computer. At this time, the sound of the computer fan, the sound of ty...
