Problems solved by technology

[0005] In view of the defect that the existing noise reduction processing methods cannot effectively remove the inherent strong internal noise of the intelligent robot itself, the present invention provides a device and method for improving the robustness of speech recognition. Regarding the noise intensity, microphones and microphone arrays are set up at different positions to receive corresponding sound signals, and then adaptive noise reduction processing and beamforming processing are implemented based on the obtained sound signals, which can effectively reduce the inherent internal strength of the intelligent voice interaction machine itself. The impact of noise, thereby significantly improving the signal-to-noise ratio of the speech signal and improving the accuracy of speech recognition

Abstract

The present invention provides a device and method for improving the robustness of speech recognition. The device and method are obtained at two different positions of the noise source position and the minimum noise energy area of ​​the body of the target device such as an intelligent voice interactive machine. Different sound signals, then implement adaptive noise reduction processing and multi-channel noise reduction algorithm processing based on the obtained sound signals, so as to effectively eliminate the inherent noise of the target device while ensuring useful voice information in the sound signal not be tampered with, so as to improve the accuracy and accuracy of speech recognition performed by the intelligent speech interaction machine.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a device and method for improving the robustness of speech recognition. Background technique [0002] With the continuous advancement of artificial intelligence technology and Internet technology, intelligent robots with human-computer interaction functions have appeared in human life and work, and such intelligent robots themselves have strong computing and processing capabilities, and can quickly respond to different emergencies It is widely used and favored because of its characteristics of dealing with different types of problems in a timely manner and in large quantities. The human-computer interaction functions of this type of intelligent robot include voice recognition or gesture recognition. Among them, speech recognition is the earliest and fastest-growing technology for intelligent robots, which can meet the needs of people and intelligent robots for...
