Abstract

The invention provides an audio processing method and an intelligent sound box. The method comprises the following steps: obtaining to-be-played audio data, and obtaining current operation informationwhich comprises an operation voltage, an operation current and an operation vibration amplitude; acquiring magnetic field interference information of the current environment, and performing noise reduction on the to-be-played audio according to the operation voltage, the operation current and the magnetic field interference information; performing voice endpoint detection on the to-be-played audio data, and performing audio segmentation on the to-be-played audio data according to a voice endpoint detection result to obtain effective audio; and performing audio noise reduction on the effectiveaudio in the to-be-played audio according to the operation vibration amplitude, and playing the to-be-played audio data after audio noise reduction. According to the invention, through obtaining themagnetic field interference information based on the current environment, noise reduction is carried out on noise data generated in different magnetic field interference environments, and the audio noise reduction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of audio processing, and in particular relates to a method for audio processing and an intelligent speaker. Background technique [0002] With the continuous advancement of technology, smart speakers have gradually become popular. In particular, smart speakers can perform data interaction with various smart devices such as smartphones and tablet computers, and are widely loved by users for their advantages of small size and light weight. The smart speaker can receive the audio data to be played pushed by the user through the mobile terminal (mobile phone, Pad, personal computer, etc.) to achieve the corresponding audio playback effect. In order to improve the user's audio-visual experience, the audio noise reduction of smart speakers has attracted more and more attention. [0003] During the use of existing smart speakers, audio noise reduction processing is performed by using filters. However, since filte...
