Problems solved by technology

However, this method requires additional hardware-assisted positioning, and its positioning accuracy requirements are high. When the positioning accuracy cannot meet the requirements, it may also lead to a decrease in noise reduction performance. Moreover, the implementation of this solution is complicated, and many scenes are difficult to completely cover, and the reliability is poor.

Abstract

The invention discloses a voice awakening method. The method comprises the following steps: acquiring a voice signal through a microphone array; respectively carrying out denoising processing on the voice signal by utilizing N beam forming denoising algorithms so as to obtain N denoising signals, wherein each beam forming denoising algorithm corresponds to one area in N areas, the areas corresponding to the different beam forming denoising algorithms are different, the union set of the N areas cover a signal acquisition area of the microphone array, and N is a positive integer greater than 1;and carrying out voice awakening according to at least one of the N denoising signals by utilizing an awakening engine. The method is capable of playing the denoising performance of the denoising algorithms to the greatest extent, and eliminating the echoes outside the beams so as to enhance the echo elimination performance, has a relatively high awakening rate and recognition rate, and is simpleto realize and easy to popularize. The invention further discloses a corresponding device, equipment and a medium.

Description

technical field [0001] The present application relates to the field of voice interaction, and in particular to a voice wake-up method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of voice recognition technology, voice interaction has gradually become a more popular control method. In order to realize voice interaction, it is first necessary to activate the device from the dormant state to the running state through voice, that is, voice wake-up is required. As the entrance of voice interaction, the wake-up effect of voice wake-up directly affects the voice interaction experience. [0003] Voice wake-up specifically refers to detecting a target keyword in a continuous voice stream to wake up a device or wake up an application. At present, the industry mainly adopts the microphone array voice enhancement method based on beamforming to realize voice wake-up. Specifically, the spatial phase information contained in ...
