Problems solved by technology

[0002] With the rise of artificial intelligence, smart speakers have also become popular. At present, the volume of smart speakers is manually set, such as touch click, slide or voice control, or it can be set to be adjusted according to time, such as automatically turning down the volume at 22 o'clock in the evening, but The volume cannot be adjusted intelligently according to the environment and scene. People often have poor listening effect due to the low sound when they are far away from the speaker, or are affected by the loud sound of the speaker when they are close to the speaker.

Abstract

The invention provides a method and system for automatically adjusting the volume of a loudspeaker box, and relates to the field of artificial intelligence. The method comprises the following steps: collecting ambient sound; extracting an MFCC characteristic value of the ambient sound so as to generate a spectrogram; inputting the spectrogram into a sound recognition model to recognize an audio type, the audio type at least comprising background sound; inputting the spectrogram into a volume recognition model to recognize the volume; if the audio type contains the user voice, reversely adjusting the volume of the sound box according to the volume of the user voice; and if the audio type does not contain the user voice, forwardly adjusting the volume of the sound box according to the volumeof the background sound. The volume of the sound box can be adaptively adjusted, and the listening experience of a user is greatly improved.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, and in particular to a method and system for automatically adjusting the volume of a speaker. Background technique [0002] With the rise of artificial intelligence, smart speakers have also become popular. At present, the volume of smart speakers is manually set, such as touch click, slide or voice control, or it can be set to be adjusted according to time, such as automatically turning down the volume at 22 o'clock in the evening, but The volume cannot be intelligently adjusted according to the environment and scene. Often people are far away from the speaker because the sound is low, and the listening effect is poor, or when people are close to the speaker, they are affected by the loud sound of the speaker. Contents of the invention [0003] A technical problem to be solved in the present disclosure is to provide a method and system for automatically adjusting the volume of a...
