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

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

A method and a device for waking up via a speech based on artificial intelligence are provided in the present disclosure. The method includes: clustering phones to select garbage phones for representing the phones; constructing an alternative wake-up word approximate to a preset wake-up word according to the preset wake-up word; constructing a decoding network according to the garbage phones, the alternative wake-up word and the preset wake-up word; and waking up via the speech by using the decoding network. Due to the data size for the garbage phones is significantly smaller than the data size for the garbage words, a problem that the data size occupied is too large by using a garbage word model in the prior art is solved. Meanwhile, as a word is composed of several phones, the garbage phones may be more likely to cover all words than the garbage words. Thus, an accuracy of waking up is improved and a probability of false waking up 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 ...
