Abstract

The invention provides a noise suppression method and device, a medium and electronic equipment. The method comprises the following steps: acquiring a low-frequency spectrum feature and a high-frequency spectrum feature of an original voice signal, and performing feature combination processing on the low-frequency spectrum feature and the high-frequency spectrum feature to obtain a frequency band energy feature; determining a current frame of voice signal and a previous frame of voice signal in the original voice signals, and performing linear domain transformation processing on the current frame of voice signal and the previous frame of voice signal to obtain spectrum characteristic parameters; performing correlation calculation on the frequency spectrum characteristic parameters and the frequency band energy characteristics to obtain cepstrum characteristics, and dimension reduction mapping processing is carried out on the cepstrum characteristics to obtain dimension reduction characteristics; and performing feature fusion processing on the dimension reduction feature and the cepstrum feature to obtain gain information, and performing noise suppression processing on the gain information to obtain a noise reduction voice signal of the original voice signal. According to the method, the noise suppression effect and efficiency of the key noise type are ensured, and the complexity of noise suppression is greatly reduced.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular, to a noise suppression method, a noise suppression device, a computer-readable medium, and electronic equipment. Background technique [0002] In various conference and other audio communication software, mic noise is a very common noise signal. The way to suppress the spraying noise is to carry out the processing of suppressing the spraying noise incidentally during the conventional noise reduction processing. [0003] However, the complexity of conventional noise reduction processing methods is relatively high, and there is no special suppression method for mic noise, so the suppression effect of mic noise cannot be guaranteed. [0004] In view of this, it is urgent to develop a new noise suppression method and device in this field. [0005] It should be noted that the information disclosed in the above background technology section is only used to enhance...
