Embodiment 1

[0030] The following describes a voice processing method provided by Embodiment 1 of the present application, please refer to the attached figure 1 , the voice processing method in Embodiment 1 of the present application includes:

[0031] In step S101, receive the voice signal to be processed;

[0032] In the embodiment of the present application, the voice signal to be processed is the voice signal received by the mobile terminal used by the user when the user makes a call.

[0033] In step S102, Fourier transform is carried out to above-mentioned speech signal, obtain the frequency spectrum of above-mentioned speech signal;

[0034] After the mobile terminal receives the voice signal of the other party in step S101, it performs Fourier transform on the voice signal to obtain the frequency spectrum of the voice signal. Wherein, the method of carrying out Fourier transform to this voice signal can be: first carry out digital sampling to this voice signal, convert this voice...

Embodiment 2

[0057] Another speech processing method provided by Embodiment 2 of the present application is described below, please refer to the attached Figure 4 , the voice processing method in Embodiment 2 of the present application includes:

[0058] In step S401, receive the voice signal to be processed;

[0059] In step S402, performing Fourier transform on the above-mentioned speech signal to obtain the frequency spectrum of the above-mentioned speech signal;

[0060] In the second embodiment of the present application, the above-mentioned steps S401-S402 are executed in the same way as the steps S101-S102 in the first embodiment, and details can be referred to the description of the first embodiment.

[0061] In step S403, calculate the ratio of the signal energy of the above-mentioned spectrum in each preset sub-frequency band to the signal energy of the above-mentioned spectrum in the preset frequency band;

[0062] In the embodiment of the present application, the above-menti...

Abstract

The present application provides a voice processing method, a voice processing device, and a mobile terminal. The voice processing method comprises: receiving a voice signal to be processed; performing Fourier transform on the voice signal to obtain a frequency spectrum of the voice signal; increasing a signal amplitude of a preset frequency band in the frequency spectrum, and decreasing a signalamplitude of the frequency bands other than the preset frequency band in the frequency spectrum, and obtaining the processed frequency spectrum, wherein the preset frequency band is a frequency band covering a human vocal frequency range; performing inverse Fourier transform on the processed frequency spectrum to obtain a processed voice signal. The technical solution can solve the technical problem that when a user answers the phone or calls a person, if the person is in a noisy environment, the voice received by the user includes a large amount of noise; and the call quality can be improved.

Description

technical field [0001] The present application belongs to the technical field of speech processing, and in particular relates to a speech processing method, a speech processing device, a mobile terminal and a computer-readable storage medium. Background technique [0002] Mobile terminals (such as mobile phones, telephone watches, etc.) have become the most mainstream communication tools in today's society, and users often use mobile terminals to make and receive calls. However, if the user is in a noisy environment when the user is making a call, the voice received by the user will contain a large amount of noise, which will seriously affect the call quality. Contents of the invention [0003] In view of this, the present application provides a voice processing method, a voice processing device, a mobile terminal and a computer-readable storage medium, which can solve the problem that the user hears if the other party is in a noisy environment when the user is making a ca...
