Abstract

The invention provides a noise reduction method, a noise reduction device and a terminal, wherein the noise reduction method comprises the steps of determining noise properties of received voice information; determining a target noise reduction manner from a plurality of pre-set noise reduction manners according to the noise properties of the voice information, and reducing noise of the voice information, wherein the plurality of pre-set noise reduction manners comprise a hardware noise reduction manner and a software noise reduction manner. By means of the technical scheme provided by the invention, the noise reduction manner suitable for a current scene is determined according to the noise properties of the voice information, and therefore, input of the voice information can be enhanced; the voice recognition rate is increased, and further, the best noise reduction and voice recognition effects are achieved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a noise reduction method, a noise reduction device and a terminal. Background technique [0002] In current terminals, hardware noise reduction or software noise reduction is generally used to perform noise reduction processing on voice information, so as to meet different needs of users for noise processing. However, the two noise reduction methods cannot be used at the same time, and the switching noise reduction method in the related art often requires the user to manually set the noise reduction level and other operations, but cannot automatically switch the noise reduction method, which has great limitations. Poor and degrades user experience. [0003] Therefore, a new technical solution is needed, which can automatically select a noise reduction method for the user according to actual needs. Contents of the invention [0004] Based on the above problems, the ...
