Abstract

The present application discloses a method, device and electronic device for judging wake-up by voice, including: acquiring input voice, and a first model judges whether to wake up according to the input voice; if the judgment result is wake-up, returning the wake-up length to determine the wake-up voice segment ; Input the spectrogram of the wake-up speech segment into a second model to obtain a wake-up judgment result, wherein the second model is a two-class network model trained according to a large number of spectrograms of the wake-up speech segment. In the method, device and electronic device for judging wake-up by voice, when the result of the first judgment is wake-up, the wake-up voice segment is intercepted, and the wake-up voice segment is further judged according to the spectrogram of the wake-up voice segment. And the second judgment is based on the direct and effective wake-up voice segment, so it can eliminate false wake-up that may be caused by some environmental factors, and improve the wake-up performance of the device.

Description

technical field [0001] The present invention relates to data processing technology, more specifically, relates to a voice wake-up judging method, device and electronic equipment. Background technique [0002] Voice wake-up is an entrance for human-computer interaction. At present, more and more smart devices use voice wake-up technology as the basic configuration technology of products. [0003] Existing wake-up technologies mainly include two types. One is to directly establish an end-to-end model. The principle is to extract features from a large number of voices and input the extracted features into the neural network to obtain the posterior probability of each frame of voice. When the probability is greater than the threshold, it is determined to wake up; the second is based on the structure of the hidden Markov model, and the optimal path is obtained through the Viterbi algorithm to judge whether to wake up. [0004] However, the above-mentioned wake-up technology has ...
