Abstract

The invention discloses an intelligent speech denoising communication method and device. To-b-denoised noisy speech data are received and preprocessed, thus the noisy speech data in a predetermined format are obtained, the noisy speech data in the predetermined format are sent to an adaptive filter bank denoising algorithm, a deep neural network denoising algorithm and a wiener filtering denoisingalgorithm to be denoised, a plurality of channels of denoised speech data are subjected to denoising quality assessment, a denoising quality score list is generated, and the channel of desnoised speech data, with the highest denoising quality score, in the denoising quality score list are selected to generate a final denoising speech file. Aiming at the characteristic that different technologiesare suitable for solving specific noise speech, final results of all methods can be selected to be combined to obtain the best denoising effect, meanwhile good adaptability is also achieved, the problem that a simplex denoising method cannot be suitable for noise situation diversity is solved, and various defects generated by using a simplex denoising technology are avoided.

Description

technical field [0001] The invention relates to the technical field of speech noise reduction, in particular to an intelligent speech noise reduction communication method and device. Background technique [0002] With the development of speech technology, speech recognition is gradually becoming popular in daily life. In various scenarios of daily use, due to the existence of various noises and equipment signal interference, the voice quality and clarity will be affected, and it will bring about a sharp decline in the communication quality of the voice communication system. [0003] The existing mainstream speech noise reduction techniques mainly include spectral subtraction noise reduction and filter-based noise reduction methods. Among them, spectral subtraction noise reduction converts the speech signal from the time domain to the frequency domain, and then removes the influence of the noise signal from the spectral signal. The noise reduction method based on the filter...
