Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] The artificial intelligence-based voice wake-up method and device according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0036] figure 1 It is a schematic flowchart of an artificial intelligence-based voice wake-up method provided by an embodiment of the present invention.

[0037] Because in the prior art, wake-up words and garbage words are usually connected in parallel to form a decoding network for wake-up, but when constructing garbage words, if th...

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 ...
