Embodiment Construction

[0078] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0079] see figure 1 , shows a schematic flowchart of the wake word evaluation method of the present disclosure. Can include the following steps:

[0080] S101. Obtain a word to be evaluated input by a user.

[0081] In the disclosed solution, the user can set a word to be evaluated to be used as a wake-up word according to the user's own needs. The composition of the words to be evaluated in this disclosure plan is not specifically limited, and the same language can be used, or multiple languages ​​can be mixed. For example, the words to be evaluated are "Hello iflytek", "hello iflytek", "hello iflytek", etc. The details can be set by the user according t...

Abstract

The invention provides a wake-up word estimation method and device, a storage medium and an electronic device. The method comprises: acquiring words to be estimated, input by a user; extracting estimation characteristics of the words to be estimated, wherein the estimation characteristics are used for indicating distinctiveness of the words to be estimated, in acoustic and/or semantic aspect; using the estimation characteristics of the words to be estimated as input, processing with a pre-constructed wake-up word estimation model, and determining whether the words to be estimated are suitablefor serving as wake-up words. The wake-up word estimation method and device, the storage medium and the electronic device help improve the accuracy of wake-up word estimation results, thereby improving wake-up effect of wake-up words set by a user.

Description

technical field [0001] The present disclosure relates to the technical field of voice signal processing, and in particular, to a wake-up word evaluation method and device, a storage medium, and an electronic device. Background technique [0002] Voice wake-up technology is an important branch in the field of voice signal processing technology, and has important applications in smart homes, smart robots, smart cars, smart phones, etc. [0003] In the actual application process, the smart terminal captures the voice data input by the user, and uses the pre-built wake-up model to recognize the wake-up word. If the voice data is recognized as the wake-up word, the wake-up is successful; otherwise, the wake-up fails. [0004] In order to improve the user experience, the user can set personalized wake-up words according to requirements. At the same time, in order to ensure the wake-up effect, when the user sets the wake-up word, it is necessary to first evaluate the wake-up word ...
