Voice wakeup method and voice wakeup device based on artificial intelligence

Abstract

The invention proposes a voice wakeup method and a voice wakeup device based on artificial intelligence. The voice wakeup method comprises the following steps: acquiring pronunciation information corresponding to a custom wakeup word; acquiring approximate pronunciation information corresponding to the pronunciation information; and building a wakeup word recognition network according to a preset spam word list, the pronunciation information and the approximate pronunciation information so as to recognize voice input by a user according to the wakeup word recognition network and determine whether or not need to perform a wakeup operation according to the recognition result. According to the embodiments of the invention, a wakeup word recognition network can be built dynamically for different custom wakeup, so that the accuracy of wakeup is enhanced effectively, the rate of false alarm is reduced, and the wakeup efficiency is improved. The device has smaller memory footprint and low power consumption.

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 can respond in a manner similar to human intelligence. Research in this field includes robotics, language recognition, image recognition, natural language processing and expert systems, etc. [0003] Voice wake-up technology is an important branch of voice recognition technology. Currently, it has important applications in vehicle, navigation, smart home, etc. It is used ...

AI Technical Summary

Problems solved by technology

[0004] Method 1: When the user defines the wake-up word, the technician redevelops or modifies the wake-up program according to the user-defined wake-up word, and then the user downloads and uses it, which is costly and takes a long time;

[0005] Method 2 directly replaces the wake-up words in the original wake-up network with user-defined wake-up words. However, this method adopts the same recognition strategy for all wake-up words, so there are problems of low wake-up accuracy rate and high false alarm rate.

[0006] The third way is to recognize the voice input by the user through the general voice recognition module to determine whether the voice input by the user contains the wake-up word. However, the general voice recognition model consumes a lot of power and consumes electricity, while the wake-up technology requires real-time monitoring. Therefore, this method will lead to a large power consumption of the device, which is not conducive to the use of localized wake-up technology
