Abstract

The disclosure relates to a method and device for enhancing human voice of an audio signal, relates to the field of multimedia technology, and can solve the technical problem of human voice dialogue enhancement in real-time audio file transmission with relatively low data processing complexity. The method includes: performing windowing and framing processing on the original audio signal to obtain a plurality of audio signal segments; obtaining fundamental frequency information and a plurality of characteristic parameters of each audio signal segment according to the plurality of audio signal segments; wherein, each audio signal The multiple characteristic parameters of the segment include the characteristic parameters that each audio signal segment is divided into multiple Bark subbands on the amplitude spectrum; each audio signal segment is sequentially enhanced according to the neural network algorithm, and each audio signal segment is respectively obtained The human voice enhancement signal of the signal segment; the human voice enhancement signal of each audio signal segment is sequentially stacked and added to obtain the target enhancement signal.

Description

technical field [0001] The present disclosure relates to the field of multimedia technology, and in particular to a method and device for enhancing human voice of an audio signal. Background technique [0002] With the development of multimedia technology, live video and video sharing have become a fashionable and common way of entertainment. However, in addition to human voices, there are usually obvious noises in the video, such as wind, ringtones, or traffic horns, etc., especially when users record videos outdoors or do live video broadcasts, the external environment is usually noisy, and these noises make It is difficult for users to hear the human voice dialogue in the video clearly, which seriously affects the user's hearing effect. [0003] The current technical solutions for vocal dialogue enhancement use Recurrent Neural Network (RNN) or Convolutional Neural Network (CNN) for deep learning. Although better vocal enhancement effects can be obtained, the network Th...
