Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings.

[0030] In order to facilitate understanding of the sound pickup and noise reduction method provided in this application, its application scenario is firstly explained. The sound pickup and noise reduction method is applied to a voice air conditioner. At present, due to the influence of external noise and air conditioner noise in the use of voice-based air-conditioning products, there are bottleneck problems such as poor wake-up effect and false wake-up after long-term operation, which need to be optimized.

[0031] The present application provides a sound pickup and noise reduction method, and the sound pickup and noise reduction method is applied to a voice air conditioner. refer to figure 1 , figure 1 A schematic flow chart of the sound pickup and noise reduction method ...

Abstract

The invention provides a pickup noise reduction method and a voice air conditioner. The pickup noise reduction method is applied to the voice air conditioner. The pickup noise reduction method comprises the steps: detecting the direction of a user; shielding noise in other directions according to the detected direction of the user; picking up a voice control command of the user; and performing noise reduction processing on the voice control command according to the bottom noise frequency and the wind noise frequency of the air conditioner. According to the pickup noise reduction method, the tone quality loss of the voice control command can be effectively reduced, and clearer effective information can be obtained, so that the bottleneck problems that the voice air conditioner awakening effect is poor, and awakening is conducted by mistake after long-time operation can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a sound pickup and noise reduction method for a voice air conditioner. Background technique [0002] With the development of technology, air conditioners have also developed a voice control mode, but when the air conditioner is controlled by voice, it is easily affected by the noise of the external environment and the noise of the air conditioner itself. As a result, the current voice air conditioner products have poor wake-up effect and run for a long time Bottleneck problems such as false wake-up, aiming at the problem of poor wake-up effect and long-term running false wake-up problems. Contents of the invention [0003] This application provides a sound pickup and noise reduction method and a voice air conditioner, which are used to improve bottleneck problems such as poor wake-up effect and false wake-up during long-term operation of existing voice air-co...
