Abstract

The invention discloses a noise reduction method, a noise reduction device and a communication terminal which are used for solving the noise interference problem in communication terminal conversation. The noise reduction method comprises controlling a first voice frequency input device to collect noise in an environment where the communication terminal is located; carrying out spectral analysis comparison on the environment noise and pre-stored scene noise in the communication terminal to obtain a comparison result; and according to the comparison result, calling noise reduction parameters corresponding to the environment noise, and according to the noise reduction parameters, separating user sound collected by a second voice frequency input device. The noise reduction method, the noise reduction device and the communication terminal have the advantages that through man-machine interaction, an exclusive button is set, a recording menu is called by triggering the button, a user can record noise in a user-defined mode and set the noise reduction parameters, in a conversation state, the user sound is separated through scene noise identification, conversation quality of the communication terminal is improved, and noise reduction cost of the communication terminal is saved.

Description

technical field [0001] The present invention relates to noise reduction processing of communication equipment, and more specifically, to a noise reduction method, device and communication terminal. Background technique [0002] With the rapid development of science and technology, people's requirements for call quality are getting higher and higher, and call noise reduction is the product of coping with quality improvement. Most of the existing noise reduction methods are realized by means of noise reduction algorithms, structural design, circuits, etc. For example, the utility model patent with application number: 200820051730.4 discloses a noise reduction device and a noise reduction mobile terminal. The noise reduction device It includes: a noise acquisition module for collecting noise signals; a noise reduction module for offsetting or weakening noise signals in audio signals containing noise by using the noise signals collected by the noise acquisition module, and the i...
