Abstract

The invention discloses a processing method for voice noise reduction of the Internet of Vehicles, and the method comprises the steps of adjusting a signal-to-noise ratio according to the voice and noise energy values, and zooming a noise signal, and obtaining different noise voices; establishing a noise reduction model; and on the basis of a noise reduction result of the noise reduction model, intercepting a part of environmental noise, and removing a mute part which is below -35 dB and lasts for more than 2 seconds by using a voice processing tool according to the fact that the average value of voice energy is greatly concentrated below -35dB. According to the method, an end-to-end deep learning network is used in an actual vehicle-mounted voice processing scene with larger wind dryness, and the step of voice conversion processing in a traditional method is omitted; more training samples are obtained by adjusting different signal-to-noise ratio parameters, the generalization ability of the model is improved, and a sample after model processing is saved after the mute part is removed, so that the storage space is saved.

Description

technical field [0001] The invention belongs to the technical field of online car-hailing, and in particular relates to a processing method for voice noise reduction in the Internet of Vehicles. Background technique [0002] The recording of the online car-hailing operation process is the best evidence to restore the driver and passenger process. For example, in the dispute between the driver and the passenger, when the responsibility cannot be clearly determined through the appeal reasons of both parties, the recording record is retrieved and the responsibility is determined based on the real recording data. square. Most of the car recordings are windy and windy, and they are also mixed with navigation broadcast sounds during driving, which are mixed with human voices, making it difficult to remove. In addition, the recording of the online car-hailing driving process is the whole process of recording with the start and end of the order, ranging from a few minutes to a few ...
