Embodiment Construction

[0100] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0101] First, some nouns involved in various embodiments of the present invention are defined and described:

[0102] 1. Voiced signal: refers to the voice signal collected by the microphone due to the vibration of the vocal cords of the speaker.

[0103] 2. Unvoiced signal: refers to the voice signal collected by the microphone due to the non-vibration of the vocal cords of the speaker. The voiceless signal includes a normal voiceless signal and a mic signal.

[0104] 3. Mic spray signal: refers to the voice signal generated by the airflow sprayed from the speaker's mouth to the microphone.

[0105] 4. The normal unvoiced signal refers to the voice signal except the mic signal in the unvoiced signal, which is the unvoiced signal nor...

Abstract

The invention discloses a voice signal processing method and device, belonging to the technical field of audio processing. The method includes: acquiring a voice signal collected by a microphone; detecting whether the voice signal belongs to an unvoiced signal, and the unvoiced signal includes a normal unvoiced signal and a microphone-spraying signal, and the microphone-spraying signal refers to a voice signal generated by airflow spraying from the speaker's mouth to the microphone; If the voice signal belongs to an unvoiced signal, then detect whether the voice signal belongs to a microphone-injection signal; if the voice signal belongs to a microphone-injection signal, the voice signal is suppressed, and the suppression process includes at least one of energy attenuation processing, deletion processing and silent processing kind. The invention solves the problems of poor real-time performance and low efficiency in the processing mode of spraying wheat in the related art; improves the real-time performance and efficiency of spraying wheat processing, and does not need manual post-repair, and achieves the effect of automatic detection and suppression of spraying wheat.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a voice signal processing method and device. Background technique [0002] Microphones are often used in people's daily work and life. When using a microphone to speak or sing, I often encounter the trouble of mic spitting. [0003] For mic spraying, the commonly used processing methods include the following two methods: first, when people use the microphone, control the distance and angle between the mouth and the microphone to reduce the occurrence of mic spraying as much as possible; The way to repair it is for the technician to find out the position of the mic from the recorded audio and perform manual attenuation. [0004] In the process of realizing the present invention, the inventor found that the above-mentioned technology has at least the following problems: the above-mentioned first method cannot completely avoid the occurrence of wheat spraying, and the abo...
