Title: VOICE WAKE-UP METHOD AND DEVICE
Abstract:
The invention discloses a voice wake-up method and a device. The voice wake-up method comprises steps as follows: acquiring a to-be-processed voice signal (S11); decoding the voice signal according to a pre-generated searching space to obtain a voice recognition result, wherein the searching space comprises a path where an inverse model is located, and the inverse model comprises a first inverse model generated by training word segmentation results of wake-up words (S12); determining whether the words with the preset number of characters contains at least part of characters in the wake-up words when the preset number of characters before the voice recognition result is obtained (S13); and directly determining cancellation of wake-up operation if at least part of characters in the wake-up words are not contained, and ending the decoding of the voice signal (S14). The method has the advantages that the mistaken wake-up rate can be reduced, and the power consumption can be reduced.
