Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] The embodiment of the present invention discloses a volume adjustment method and system. After the audio signal is obtained from the environment, the audio signal is divided into multiple short-term audio frames. When the short-term energy in the short-term audio frame is greater than the short-term energy Threshold, when the short-term frequency is greater than the short-term frequency threshold, it is determined that the corresponding short-term audio ...

Abstract

The invention discloses a method and a system for adjusting volume, after the audio signal is collected from the environment, dividing the audio signal into a plurality of short-time audio frames, when the short-term energy in the short-term audio frame is greater than the short-term energy threshold, when the short-time frequency is greater than the short-time frequency threshold, determining that the corresponding short-time audio frame is in a speech mixing state, by processing all the short-time audio frames in the speech mixing state, the short-time audio frames higher than the referenceaudio frames are lowered to the reference audio frames, and the short-time audio frames lower than the reference audio frames are raised to the reference audio frames, thereby realizing automatic volume adjustment. The invention solves the problem that the volume fluctuates greatly when the voice interacts, and saves the process that the user manually adjusts the volume of the player, thereby improving the voice interaction experience and enabling the user to carry out normal voice communication.

Description

technical field [0001] The present invention relates to the technical field of voice adjustment, and more specifically, to a volume adjustment method and system. Background technique [0002] In real-time multi-person voice interaction, such as live broadcast, due to various factors, such as new participants joining, environmental noise, and equipment problems, sometimes the volume suddenly increases or decreases, or harsh noises are generated, commonly known as "Fried wheat", therefore, will affect normal voice communication, which in turn may affect other user behaviors, such as live broadcast and games. [0003] When the "fried wheat" phenomenon occurs, the user is required to manually adjust the volume of the player, which is extremely inconvenient for the user, and the existing voice real-time communication software cannot avoid the "fried wheat" phenomenon. Therefore, how to provide a volume adjustment method and system to realize automatic adjustment of the volume ha...
