Abstract

The invention discloses a noise reduction method and device, head-mounted display equipment and a readable storage medium, and the method comprises the following steps: obtaining a first audio signalreceived by a main microphone, and extracting first voice intensity and first noise intensity in the first audio signal; acquiring a second audio signal received by the auxiliary microphone, and extracting second voice intensity and second noise intensity in the second audio signal; comparing the first noise intensity with the second noise intensity to generate a proportionality coefficient; adjusting the sound intensity of the first audio signal or the second audio signal according to the proportionality coefficient to enable the noise intensity in the first audio signal and the noise intensity in the second audio signal to be the same; and processing the adjusted difference between the first audio signal and the second audio signal. According to the technical scheme, noise interference can be effectively eliminated, and voice distortion is avoided.

Description

technical field [0001] The present invention relates to the technical field of voice control, in particular to a noise reduction method, device, head-mounted display device and readable storage medium. Background technique [0002] During the process of receiving voice by the microphone, usually due to the influence of external environmental sound, the received voice command usually includes external noise. Especially in the background of loud noise environment, due to the interference of noise, the voice will be distorted. [0003] The above content is only used to assist in understanding the technical solution of the present application, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] Based on this, it is necessary to provide a noise reduction method, device, head-mounted display device and readable storage medium for the problem of voice distortion due to the interference of the external environment during the proce...
