[0125] Based on the first embodiment, a second embodiment of the speech separation method of the present invention is proposed. In this embodiment, step S110 includes:

[0126] Step S111, acquiring a time-domain signal of noisy speech information;

[0127] Step S112, filtering the time-domain signal of the noisy speech information to obtain the filtered time-domain signal of the noisy speech information;

[0128] Step S113, performing Fourier transform on the filtered time-domain signal of the noisy speech information to obtain a frequency-domain signal of the noisy speech information.

[0129] In this embodiment, it can be understood that the dynamic signal can be represented by the time axis, and the dynamic signal can also be represented by the frequency axis. In the method of the present invention, the noisy speech information is converted into a function of time, that is, the noisy speech information is passed through The time axis represents the dynamic signal of the no...

Abstract

The invention discloses a speech separation method and device, a mobile terminal and a computer readable storage medium. The speech separation method comprises the following steps of acquiring noisy speech information, and extracting a feature vector of the noisy speech information; inputting the feature vector into a speech separation model, and acquiring a target amplitude spectrum correspondingto the feature vector; and carrying out postprocessing on the target amplitude spectrum in order to obtain target speech information. Through the adoption of the speech separation method, noise can be separated from noisy speech effectively and rapidly in order to obtain pure speech information.

Description

technical field [0001] The invention relates to the field of voice separation, in particular to a voice separation method, device, mobile terminal and computer-readable storage medium. Background technique [0002] In a noisy environment, there are often many different sound sources at the same time, and in the process of sound wave transmission, the sound waves emitted by different sound sources and between the direct sound and the reflected sound will be superimposed in the propagation medium to form Complex hybrid sound waves. Therefore, in the field of speech recognition, how to separate clean speech information in a noisy environment is a technical problem to be solved urgently. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a voice separation...
