Abstract

Embodiments of the present invention provide an acoustic model optimization method, device, and voice wake-up method, device, and terminal, wherein the acoustic model optimization method includes: receiving a voice signal, extracting an acoustic feature parameter of the voice signal; judging whether the acoustic feature parameter is Corresponding to the set user; when the acoustic feature parameter corresponds to the set user, use the acoustic feature parameter to modify the statistical parameters of the current acoustic model, so as to optimize the current acoustic model. The acoustic model optimized by the acoustic model optimization method provided by the embodiment of the present invention can be adapted to a specific user.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, and more specifically, to an acoustic model optimization method, device, and voice wake-up method, device and terminal. Background technique [0002] At present, the user's habit of using voice to interact is forming. In the current voice interaction process, the user needs to light up the screen of the terminal device, unlock the screen, find and start the voice software installed on the terminal device before using voice to interact. This voice interaction process does not completely release the hands. Voice wake-up technology can just solve this problem. Voice wake-up technology can wake up the phone when the phone is locked and automatically start the voice software, which can bring users a better voice interaction experience. [0003] The voice wake-up technology involves the recognition of the user's voice. In order to improve the accuracy of voice wake-up, it is necessa...
