Voice wake-up method, electronic device, and computer-readable storage medium

Abstract

A voice wake-up method, an electronic device, and a computer-readable storage medium are provided. The voice wake-up method comprises collecting an original voice signal input by a user; generating pulse density modulation data according to the original voice signal; decoding the pulse density modulation data to generate decoded data; performing preprocessing and feature extraction processing on the decoded data to generate voice features; performing pattern matching on the voice features according to a hidden Markov model to generate a recognition result; and waking up an external processor of the electronic device according to the recognition result. In the voice wake-up method, a voice wake-up function of the electronic device is realized, which reduce the power consumption of the electronic devices while improving the accuracy of voice wake-up.
