Problems solved by technology

There will inevitably be background noise in the voice signal input by the user to the mobile terminal, and the existence of background noise seriously affects the quality of the voice signal, and reduces the success rate and accuracy of voice recognition for the voice signal
For example, when a user uses a mobile terminal to make a voice call in a driving vehicle, they are often interfered by environmental signals such as wind noise signals, audio signals output by multimedia applications, etc., resulting in the failure of voice recognition during the voice call. low rate and accuracy

Abstract

The invention discloses a voice noise reduction method, a voice noise reduction system, equipment and a storage medium. The voice noise reduction method comprises the steps that a vehicle machine acquires a user voice signal input into a mobile terminal by a user in a vehicle in real time; and after the vehicle machine receives a starting instruction for voice noise reduction, the acquired user voice signal is used as a target voice signal for noise reduction processing, and then the target voice signal after noise reduction processing is transmitted to the mobile terminal. The invention provides the voice noise reduction method, the voice noise reduction system, the equipment and the storage medium. According to the embodiment of the invention, noise reduction is carried out on the user voice signal input into the mobile terminal by the user in the vehicle through the vehicle machine, so that the mobile terminal obtains the user voice signal after noise reduction processing, the quality of the voice signal can be improved, and the success rate and accuracy of the voice recognition of the voice signal can be improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a speech noise reduction method, a speech noise reduction system, equipment and a storage medium. Background technique [0002] With the continuous development of the communication industry, voice functions of mobile terminals such as mobile phones are widely used in scenarios such as voice calls and voice recognition. Background noise inevitably exists in the voice signal input by the user to the mobile terminal, and the existence of the background noise seriously affects the quality of the voice signal, and reduces the success rate and accuracy of voice recognition for the voice signal. For example, when a user uses a mobile terminal to make a voice call in a driving vehicle, they are often interfered by environmental signals such as wind noise signals, audio signals output by multimedia applications, etc., resulting in the failure of voice recognition during the voice call. rate and a...
