Abstract

The invention discloses a noise reduction method, device, head-mounted display device, and readable storage medium. The method includes: acquiring a first audio signal received by a main microphone, and extracting a first voice intensity and a second audio signal from the first audio signal. A noise intensity; obtain the second audio signal received by the auxiliary microphone, extract the second voice intensity and the second noise intensity in the second audio signal; compare the first noise intensity and the second noise intensity, and generate a proportional coefficient; according to the proportional coefficient, Adjusting the sound intensity of the first audio signal or the second audio signal, so that the noise intensity in the first audio signal and the second audio signal is the same; and processing the difference between the adjusted first audio signal and the second audio signal. The technical scheme of the invention can effectively eliminate noise interference and avoid voice distortion.

Description

technical field [0001] The present invention relates to the technical field of voice control, and in particular, to a noise reduction method, a device, a head-mounted display device and a readable storage medium. Background technique [0002] In the process of receiving the voice with the microphone, usually due to the influence of external environmental sounds, the received voice commands usually include external noises. Especially in the background of loud noise environment, due to the interference of noise, the speech is distorted. [0003] The above content is only used to assist the understanding of the technical solutions of the present application, and does not mean that the above content is the prior art. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary to provide a noise reduction method, a device, a head-mounted display device and a readable storage medium for the problem of voice distortion due to the interference of the external environment dur...
