Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0032] The embodiment of the present application relates to artificial intelligence (AI) and machine learning (Machine Learning, ML). By combining AI and ML, the features in the audio signal can be mined and analyzed, so that the device can perform more accurate audio signal processing. Identification processing, from which the spectral features of noise signals such as echoes are determined, so as to reduce or even eliminate the adverse effects of this part of noise signals on the original audio signal. Among them, AI is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best re...

Abstract

The invention provides a signal processing method, a device and equipment and a computer readable storage medium. The method comprises the following steps: collecting an audio signal to-be-processed,and extracting spectrum characteristics of the audio signal to be processed, wherein the spectrum characteristics comprises N-dimensional logarithm energy spectrum characteristics; performing callingon a noise optimization model to process the logarithm energy spectrum features, and obtaining M-dimensional noise correction coefficients corresponding to the N-dimensional logarithm energy spectrumfeatures, and wherein N and M are positive integers; and calculating the N-dimensional logarithm energy spectrum feature and the M-dimensional noise correction coefficient to obtain a processed audiosignal. According to the embodiment of the invention, the noise correction coefficient is generated through the noise optimization model, and the noise in the audio signal to be processed is reduced or eliminated through the noise correction coefficient, so that the communication quality is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a signal processing method, device, equipment and computer-readable storage medium. Background technique [0002] With the continuous development of communication technology, people's requirements for signal quality continue to increase, especially in some scenarios such as using computer networks and mobile communication networks to hold online conferences. Minimize the unnecessary signals that are input along with the voices of the participants. [0003] In one scenario, the unnecessary signal mainly refers to a noise signal, and the noise signal may be some unwanted echo audio signals. In the multi-party teleconference scenario, there will be a situation where multiple participants speak at the same time. At this time, the local voice communication device not only plays the voices of participants from other regions, but also collects the local voices of the local pa...
