Voice noise reduction method and intelligent electronic equipment

Abstract

The invention relates to the intelligent electronic field and particularly relates to a voice noise reduction method and intelligent electronic equipment. The method comprises steps that S100, multiple frequency band scopes are preset, and a noise elimination signal corresponding to each frequency band scope is set; step 200, an audio signal is received, and a frequency band of the audio signal is acquired; step 300, at least one frequency band scope corresponding to the frequency band is selected, and noise elimination signals in the frequency band scope are merged with the audio signal; and S400, noise elimination processing is carried out after merging, and an audio signal after noise elimination is outputted. The method is advantaged in that through setting multiple different frequency bands, multi-frequency band noise elimination for noise is carried out, and the noise elimination effect is better, actual application is satisfied, and client experience is improved.

Description

technical field [0001] The invention relates to the field of intelligent electronics, in particular to a speech noise reduction method and intelligent electronic equipment. Background technique [0002] With the improvement of people's quality of life, more and more intelligent robots have entered the home service industry. This is not only a high-tech industry with great application prospects, but also an important hot spot in the current research of intelligent robots, and has formed a huge market. [0003] At present, there are many intelligent robots on the market that can interact with humans by voice. They can either interact with humans by voice, or transmit received voices to humans, which reflects their high degree of intelligence. However, due to the complex living environment Diversity, when human beings interact with intelligent robots, they will inevitably transmit the noise in the living environment to intelligent robots, resulting in intelligent robots being ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many intelligent robots on the market that can interact with humans by voice. They can either interact with humans by voice, or transmit received voices to humans, which reflects their high degree of intelligence. However, due to the complex living environment Diversity, when humans interact with intelligent robots, they will inevitably transmit the noise in the living environment to intelligent robots, causing intelligent robots to be unable to accurately distinguish which is noise and which is speech, and cannot accurately extract the information that needs to be processed. Voice, which seriously affects the communication and interaction of voice, and reduces the user experience

[0004] In the prior art, the elimination of noise is too complicated and the effect is not good. At the same time, a single way of eliminating noise will produce large errors in practical applications, making the effect of noise removal unsatisfactory.
