Voice awakening method and device based on artificial intelligence

Abstract

The invention provides a voice awakening method and a voice awakening device based on artificial intelligence, wherein the method comprises the following steps: clustering various phonemes so as to select out garbage phonemes for expressing all phonemes; in accordance with an awakening word which is set in advance, constructing a counter-awakening word similar to the awakening word; and constructing a decoding network in accordance with the garbage phonemes, the counter-awakening word and the awakening word, so that voice awakening can be implemented by virtue of the decoding network. Since the garbage phoneme is obviously less than a garbage word in data volume, the problem of the prior art that a garbage word model occupies an excessively high data volume is solved; meanwhile, since each word is constituted by a finite number of phonemes, the garbage phoneme, in comparison with the garbage word, can cover all words more comprehensively, so that awakening precision is enhanced and a probability of incorrect awakening is reduced.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to an artificial intelligence-based voice wake-up method and device. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that responds in a manner similar to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural language processing and expert systems, etc. Among them, the most important application aspect of artificial intelligence is speech recognition technology. [0003] The voice wake-up technology is one of the important directions in ...

AI Technical Summary

Problems solved by technology

[0006] For this reason, the first object of the present invention is to propose a method of voice wake-up based on artificial intelligence, to construct a garbage phoneme model by utilizing garbage phonemes, to solve the problem that the garbage word model in the prior art takes up too much data, and at the same time, Use junk phonemes to represent all voices, improve the wake-up accuracy and reduce the probability of false wake-up
