Judgment method and device of voice wakeup, and electronic equipment

Abstract

The application discloses a judgment method and device of voice wakeup, and electronic equipment. The method comprises the following steps: acquiring input voice, wherein a first model judges whetherto wake up according to the input voice; if the judgment result is to wakeup, returning to the wakeup length, and determining a wakeup voice segment; inputting a spectrogram of the wakeup voice segment to obtain a wakeup judgment result, wherein the second model is a dichotomy network model obtained according to the spectrogram training of a large amount of wakeup voice segments. Through the judgment method and device of voice wakeup, and the electronic equipment disclosed by the application, the wakeup voice segment is intercepted when the first judgment result is wakeup, and then whether towake up is further judged according to the spectrogram of the wakeup voice segment, the two-layer judgment is performed in the process, and the second judgment depends on the direct and effective wakeup voice segment, the mistaken wakeup caused by a certain environment elements can be eliminated, and the wakeup performance of the equipment is improved.

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 ...
