Abstract

The embodiment of the invention provides an acoustic model optimization method and device, a voice awakening method and device, as well as a terminal. The acoustic model optimization method comprises the steps: receiving a voice signal and extracting acoustic feature parameters of the voice signal; judging whether the acoustic feature parameters correspond to a set user; when the acoustic feature parameters correspond to the set user, using the acoustic feature parameters to correct statistical parameters of a current acoustic model, so as to optimize the current acoustic model. By adopting the acoustic model optimization method provided by the embodiment of the invention, the optimized acoustic model can perform self-adaption with the 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 for interaction is taking shape. In the current voice interaction process, users need to light up the screen of the terminal device, unlock the screen, find and start the voice software installed on the terminal device before they can interact with voice. 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] Voice wake-up technology involves the recognition of the user’s voice. In order to improve the accuracy of voice wake-up, we must try t...
