Abstract

An embodiment of the present invention provides a voice wake-up method for a smart device. The method includes: collecting audio sound sources in real time through the multi-channel microphone built in the smart device, performing echo cancellation on the audio sound sources, and determining the multi-channel audio after elimination; Perform audio enhancement in the target angle range; perform post-filtering on the enhanced audio to determine whether the post-filtered enhanced audio hits the wake-up word of the smart device, and when it hits the wake-up word of the smart device, estimate the audio source through the direction of arrival The angle information of the audio source; when the angle information of the audio source is within the preset target angle range, the smart device is woken up. The embodiment of the present invention also provides a voice wake-up system for smart devices. The embodiment of the present invention effectively suppresses noise from other directions, reduces the impact of noise on the wake-up rate, improves the recognition effect, and effectively suppresses false wake-up of other smart devices.

Description

technical field [0001] The invention relates to the field of voice wake-up, in particular to a voice wake-up method and system for smart devices. Background technique [0002] Smart TVs are gradually favored by consumers due to their ease of use and better interactivity. Open the shopping software, and you can see various types of smart TVs. However, due to the different shopping habits of each consumer, some people still like to go to offline stores to buy. In the store, the shopping guide of the store will show consumers the special functions of the smart TV, for example, the voice interaction function. [0003] When displaying the voice interaction function to consumers, it is necessary to wake up the smart TV. After waking up, the unique functions of each smart TV are displayed to consumers. [0004] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the related art: [0005] In the home envi...
