Problems solved by technology

[0003] With the existing voice wake-up technology, it is inevitable that there will be false wake-ups, and the occurrence of false wake-ups will make the user very disgusted. For example, the user is already asleep at night, but the TV is turned on by mistake and music is played.

Embodiment 1

[0016] Implementation platform: MST848 Android 8.0 platform;

[0017] Environmental detection module configuration: with thermal sensors, light sensors and distance sensors;

[0018] Wake-up module configuration: set the confidence threshold to 80;

[0019] Comprehensive judgment module configuration: it needs to be in the daytime or when the lights are turned on, someone needs to be present, and the distance between the person and the smart device is less than 3 meters;

[0020] The wake-up module receives the sound signal recorded by the smart device, and recognizes the wake-up word. If the confidence degree of the wake-up word is greater than 80, a wake-up request is sent to the comprehensive judgment module. The comprehensive judgment module acquires the detection data of the environment detection module. If the configured wake-up conditions are met, the smart device will be woken up; if the configured wake-up conditions are not met, it will be regarded as a false wake-...

Abstract

The invention discloses a voice wake-up system based on environment detection. The system comprises an environment detection module, a wake-up module and a comprehensive judgment module, wherein the environment detection module and the wake-up module are electrically connected with the comprehensive judgment module respectively; the environment detection module is used for detecting the ambient environment; the wake-up module is used for recognizing a voice signal received by intelligent equipment; when a wake-up word is recognized, a wake-up request is sent to the comprehensive judgment module; the comprehensive judgment module is used for receiving the wake-up request sent by the wake-up module, acquiring data sent by the environment detection module and judging whether intelligent equipment is waken up or not. After the system detects a voice wake-up command, whether the intelligent equipment is waken up or not is determined through a method for detecting whether people exist in theambient environment and whether the time is daytime or not or a lamp is turned on or not; the incorrect wake-up rate of the voice wake-up system is reduced and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of speech wakeup, in particular to a speech wakeup system based on environment detection. Background technique [0002] With the development of technology, smart devices such as smart phones, smart speakers and smart TVs are more and more widely used, and the use of voice wake-up technology on smart devices is also becoming more and more common. As users have higher and higher requirements for voice wake-up experience, voice wake-up technology must be continuously developed and optimized. Users are concerned about two points: one is the increase of the wake-up rate, and the other is the reduction of the false wake-up rate. [0003] With the existing voice wake-up technology, it is inevitable that there will be false wake-ups, and the occurrence of false wake-ups will make the user very disgusted. For example, the user is already asleep at night, but the TV is turned on by mistake and music is played. Cont...
