Embodiment 1

[0060] Embodiment 1 of the present invention discloses a method for enhancing sound quality, which is applied to an ARM architecture system embedded with a floating point library, such as figure 1 As shown, the method includes:

[0061] Step 101, performing speech state recognition on the acquired sound signal, so as to identify the sound signal in the speech state and the sound signal in the non-speech state in the sound signal;

[0062] Step 102, performing comfort noise conversion on the sound signal in the non-speech state to generate corresponding comfort noise;

[0063] Step 103, perform different attenuation or excitation processing on the sound signal in the speech state according to different frequency bands, and generate a sound signal with enhanced sound quality;

[0064] Step 104, perform automatic gain processing on the sound signal after sound quality enhancement.

[0065] In a specific embodiment, step 101, that is, performing speech state recognition on the a...

Embodiment 2

[0096] Embodiment 2 of the present invention also discloses a microphone, which is an ARM architecture system embedded with a floating point library, such as image 3 As shown, the microphone includes:

[0097] The identification module 201 is used to perform speech state recognition on the acquired sound signal, so as to recognize the sound signal of the sound state in the sound signal and the sound signal in the non-speech state;

[0098] A conversion module 202, configured to perform comfort noise conversion on sound signals in a non-speech state to generate corresponding comfort noise;

[0099] The first processing module 203 is used to perform different attenuation or excitation processing on the sound signal in the speech state according to different frequency bands, so as to generate a sound signal with enhanced sound quality;

[0100] The second processing module 204 is configured to perform automatic gain processing on the sound signal after sound quality enhancement...

Abstract

The embodiment of the invention provides a tone quality enhancement method and a microphone. The method comprises: voice state identification is carried out on obtained sound signals, thereby identifying sound signals in a voice state and sound signals in a non-voice state among the sound signals; comfort noise conversion is carried out on the sound signals in a non-voice state, thereby generating corresponding comfort noises; and different attenuation or excitation treatment is carried out on the sound signals in a voice state based on different frequency bands, thereby generating sound signals with tone quality enhancement; and automatic gain processing is carried out on the sound signals with tone quality enhancement. Therefore, when the sound signals are processed, the good-quality sound signals are obtained, thereby improving the user experience.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a sound quality enhancement method and a microphone. Background technique [0002] In the prior art, scenarios involving audio processing, especially in conference scenarios, due to the existence of external noise and unreasonable processing of human voices, in many conference venues due to the large space and many participants Speeches far away from the microphone may have low voices, hyphenated or unclear speech, resulting in poor user experience. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention proposes a sound quality enhancement method and a microphone to ensure user experience. [0004] Specifically, the present invention proposes the following specific embodiments: [0005] The embodiment of the present invention proposes a method for sound quality enhancement, which is applied to an ARM architecture system embedded with a...
