Abstract

The invention provides a noise suppression method, a device thereof, electronic equipment and a communication processing method. The noise suppression method comprises the steps of obtaining a first speech signal collected by a first terminal in a user speech collection state, obtaining at least one second speech signal collected by a second terminal in a non user speech collection state, and using the second speech signal to carry out noise elimination operation on the first speech signal and obtaining a third speech signal. According to the noise suppression method, the device thereof, the electronic equipment and the communication processing method, the noise suppression of the terminal of a single microphone can be carried out, and the noise suppression of the terminals of multiple microphones can be carried out too.

Description

technical field [0001] The invention relates to the field of mobile multimedia, in particular to a noise suppression method, device, electronic equipment and communication processing method. Background technique [0002] With the rapid development of computer technology, computers have entered thousands of households, bringing infinite convenience to human beings. At the same time, people's requirements for computer intelligence are getting higher and higher. Of course, the most prominent demand is reflected in the human-machine interface. If the direct dialogue between man and machine can be realized, the "machine" can understand human language, And according to its information to execute people's intentions, then this is undoubtedly the most ideal way of man-machine intelligent interface, so speech recognition emerged as a very attractive subject, many experts pointed out that speech recognition technology will be the next ten years of information technology One of the to...
