Problems solved by technology

[0002] At present, the application of product interaction through voice is more and more widely used, such as smart speakers, mobile phones, tablets, etc., but in the training process of the wake-up model, generally only wake-up words are used as training data, and the quality and quantity of training data are limited. Not high defects, therefore, easily affect the wake-up rate of the wake-up model

Embodiment Construction

[0059] In the prior art, generally only wake-up words are used as training data, and there is a defect that the quality and quantity of training data are not high. Therefore, it is easy to affect the wake-up rate of the wake-up model and seriously affect the user experience. In view of this, the present invention A method and device for updating a wake-up model are provided. The wake-up model with a higher false wake-up rate is updated. Command words and wake-up words are screened separately, and false wake-up data or distorted data are eliminated, so that the wake-up word is closer to the scheduled wake-up. At the same time, it makes the command words more in line with language logic and uses them as training data, which ensures the quality and quantity of training data, and makes the false arousal probability of the updated arousal model lower.

[0060] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further de...

Abstract

The invention provides a wake-up model updating method. The method comprises the following steps of: separating a command word and a wake-up word in original voice data; determining the probability ofcommand words according to the language model, and deleting the command words with the probability lower than a first threshold value in the command words; and inputting the wake-up word into a wake-up model, determining a score output by the wake-up model, and deleting the wake-up word with the score lower than a second threshold value in the wake-up word. Therefore, the built wake-up model withhigher false wake-up probability is updated, command words and wake-up words are screened respectively, and the wake-up words are closer to preset wake-up words by eliminating false wake-up data or distortion data. Meanwhile, the command words serve as training data, the number of the training data is guaranteed, and the false awakening probability of the updated awakening model is lower.

Description

Technical field [0001] The present invention relates to the field of voice wake-up, in particular to a method and device for updating a wake-up model. Background technique [0002] At present, the application of product interaction through voice is more and more widely used, such as smart speakers, mobile phones, tablets, etc., but in the training process of wake-up models, generally only wake-up words are used as training data, and there are quality and quantity of training data The defect is not high, therefore, it is easy to affect the wake-up rate of the wake-up model. Summary of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to provide a method and device for updating a wake-up model to solve at least one of the above technical problems. [0005] (2) Technical solution [0006] The embodiment of the present invention provides a method for updating a wake-up model, including: [0007] Separate command words and wake word...
