Awakening method and device for intelligent equipment based on artificial intelligence

Abstract

The embodiment of the invention discloses an awakening method and device for intelligent equipment, and the method comprises the steps: storing acoustic features determined according to to-be-recognized audio data in a process of verifying whether the to-be-recognized audio data contains an awakening word corresponding to intelligent equipment or not after the intelligent equipment collects the to-be-recognized audio data; after the first-level verification determines that the to-be-identified audio data contains awakening words, not waking up the intelligent equipment, but firstly performingsecond-level verification, determining an undetermined feature sequence from the stored acoustic features, and determining whether the undetermined feature sequence meets a wake-up condition or not according to the acoustic feature sequence of the awakening words; and after determining that the undetermined feature sequence meets the wake-up condition, the to-be-identified audio data passes the first-level verification and the second-level verification, and the intelligent equipment is awakened at the moment. The acoustic characteristics determined by the first-level verification are utilized,and the to-be-determined characteristic sequence is extracted according to the acoustic characteristics to perform the second-level verification, so that the error awakening frequency of the intelligent equipment is effectively reduced.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method and device for waking up smart devices based on artificial intelligence. Background technique [0002] At present, smart devices are becoming more and more popular and widely used in people's work and life. [0003] Some smart devices are in a dormant state when not providing services. When users need to use such smart devices, they can wake up the smart devices by uttering a wake-up word through voice. For example, users can wake up a dormant smart speaker through the wake-up word. [0004] However, the current related technologies have a high false wake-up rate, that is, some noise or non-wake-up word voices are misidentified as wake-up word voices, and wrongly wake up the smart device, causing the smart device to suddenly start when the user does not need it. , resulting in a bad user experience for users. Contents of the invention [0005] In order to sol...
