Abstract

The invention provides a voice wake-up method and device and a training method and device of a voice wake-up module. The voice wake-up method comprises the steps that a to-be-recognized voice signal is acquired, and the to-be-recognized voice signal comprises a wake-up word; performing wake-up word recognition on the to-be-recognized voice signal by using an acoustic model to obtain a wake-up word recognition result, the acoustic model comprising a whole word node, and the whole word node taking a word vector of a wake-up word as a weight; and performing voice wake-up according to the wake-up word recognition result, thereby improving the wake-up effect.

Description

technical field [0001] The invention relates to the technical field of voice wake-up, in particular to a voice wake-up method and device, and a voice wake-up module training method and device. Background technique [0002] Voice wake-up technology means that when a smart device detects a user's specific voice (usually a set wake-up word) in a dormant state, the device enters a waiting state and then enters a voice intelligent interaction process. Voice wake-up technology has a wide range of applications, such as Robots, mobile phones, wearable devices, smart homes, vehicles, etc. [0003] However, the modeling units of the existing voice wake-up models are often syllables or phonemes, but the wake-up words are usually whole words with 3 to 6 syllables. There is a large mismatch between the training target and the test target, and the wake-up effect is poor. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a voice wake-up...
