Noise reduction method and device, electronic equipment and readable storage medium

Abstract

The embodiment of the invention provides a noise reduction method and device, electronic equipment and a readable storage medium, and the method and device can be applied to the electronic equipment.The electronic equipment comprises a first sound collector and a second sound collector, and the installation positions of the first sound collector and the second sound collector are different; the method comprises the following steps of: based on a first sound signal collected by a first sound collector and a second sound signal collected by a second sound collector, determining an expected sound signal and an interference sound signal, performing coherent noise elimination processing on the expected sound signal based on the interference sound signal to obtain a third sound signal, and performing non-coherent noise suppression processing on the third sound signal according to the probability that voice exists in the third sound signal to obtain a target sound signal. The embodiment of the invention not only can effectively reduce the noise in the target sound signal, but also can effectively ensure that the voice in the target sound signal is not distorted.

Description

technical field [0001] The embodiments of the present application relate to the technical field of noise reduction, and in particular, to a noise reduction method, device, electronic equipment, and readable storage medium. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the quality of life, and the way of voice communication and voice interaction through electronic products has become more and more common. [0003] When the electronic device is in a noisy environment, the noise of the surrounding environment will have a great impact on the voice quality collected by the electronic device, affecting the quality of voice communication or voice interaction process, and reducing user experience and communication efficiency. For example, in the process of real-time voice communication, the surrounding environmental noise will inevitably be collected by the voice sending end. If the voice signal collected...

[0003] When the electronic device is in a noisy environment, the noise of the surrounding environment will have a great impact on the voice quality collected by the electronic device, affecting the quality of voice communication or voice interaction process, reducing user experience and communication efficiency

For example, in the process of real-time voice communication, the surrounding environmental noise will inevitably be collected by the voice sending end. If the voice signal collected by the voice sending end is not processed and then sent to the voice receiving end, the user at the voice receiving end will It will be disturbed by these environmental noises and affect normal communication. If it is not handled properly, it will distort the voice information sent by the voice sending end and affect the intelligibility of the voice.

For another example, in the field of human-computer interaction, if speech recognition is performed without processing the speech signals collected by electronic equipment, the accuracy of speech recognition will be affected and erroneous responses will appear.
