Problems solved by technology

Since it is impossible to enter the acoustic characteristics of each user's wake-up word in advance, the registered acoustic characteristics will have more personality characteristics of the registrant, resulting in the possibility of one person registering and other people using the process. The problem of low wake-up rate

Abstract

The invention discloses a voice wake-up method and device, and the method comprises the steps: sending voice information to a wake-up model for the calculation of a first score in response to the obtained voice information, and judging whether the first score is greater than or equal to a preset wake-up threshold value of the wake-up model; if the first score is greater than or equal to a wake-up threshold preset by the wake-up model, sending the voice information to a local offline recognition model for second score calculation, and judging whether the second score is greater than or equal to a wake-up threshold preset by the local offline recognition model; and if the second score is greater than or equal to an awakening threshold value preset by the local offline identification model, awakening the equipment to interact with the user. The voice information with the first score larger than or equal to the preset wake-up threshold value of the wake-up model is sent to the local offline recognition model for calculation of the second score, so that wake-up can be more accurate, false wake-up is reduced, and further, recognition can be performed more quickly by using the local offline recognition model, and recognition delay is reduced.

Description

technical field [0001] The invention belongs to the technical field of voice data processing, and in particular relates to a voice wake-up method and device. Background technique [0002] In the existing voice interaction products, the product basically has a preset wake-up word, but real users hope to be able to define the content of the wake-up word by themselves. In the existing custom wake-up technical solutions, the custom wake-up function is completed by configuring wake-up words in a relatively large wake-up model, wherein the classification nodes of the general model include all phoneme modeling units. At the same time, in order to reduce the problem of false wake-up, some existing technologies will compare acoustic features with template features, and the voice data will be sent to the general wake-up engine only when the confidence of the comparison exceeds a threshold. [0003] To implement custom wake-up words in a similar technology, the first step is to conver...
