Abstract
The Language awakening system based on environment measuring that the invention discloses a kind of, the system include context detection module, wake-up module and comprehensive judgment module, and the context detection module and wake-up module are electrically connected with comprehensive judgment module respectively；The context detection module is for detecting ambient enviroment, the wake-up module is for identifying the received voice signal of smart machine, when identifying wake-up word, wake request is issued to comprehensive judgment module, the comprehensive judgment module is used to receive the wake request of wake-up module sending and obtains the data of context detection module sending, judges whether to wake up smart machine.The system after detecting voice wake-up command, by detection ambient enviroment whether presence of people, if be daytime or the method for whether having opened lamp, to decide whether to wake up smart machine, reduce the false wake-up rate that voice wakes up system, the user experience is improved.
Description
Technical field
The present invention relates to a kind of Language awakening technical fields, and in particular to a kind of Language awakening system based on environment measuring
System.
Background technique
With the development of science and technology, smart machine such as smart phone, intelligent sound box and smart television using more and more extensive,
It is also more and more common using voice awakening technology on intelligent devices.As user wakes up the requirement of experience increasingly to voice
Height, voice awakening technology just have to last for developing and optimize.User is concerned with 2 points: one be wake-up rate raising, it is another
A is the reduction of false wake-up rate.
Existing voice awakening technology, inevitably there is an appearance of the case where false wake-up, and the generation of false wake-up, will use
Family is disliked very much, for example user has slept at night, and TV false wake-up has been switched on and has played music.
Summary of the invention
The Language awakening system based on environment measuring that in order to solve the above-mentioned technical problems, the present invention provides a kind of, this is
System after detecting voice wake-up command, by detection ambient enviroment whether presence of people, if be daytime or whether open
The method of lamp reduces the false wake-up rate that voice wakes up system to decide whether to wake up smart machine.
In order to reach above-mentioned technical effect, the present invention provides a kind of Language awakening systems surveyed based on environment measuring, should
System includes context detection module, wake-up module and comprehensive judgment module, the context detection module and wake-up module respectively with
Comprehensive judgment module electrical connection；The context detection module is used to set intelligence for detecting ambient enviroment, the wake-up module
Standby received voice signal is identified, when identifying wake-up word, i.e., issues wake request, the synthesis to comprehensive judgment module
Judgment module is used to receive the wake request of wake-up module sending and obtains the data of context detection module sending, judges whether to call out
Awake smart machine.
Further technical solution is, the context detection module includes thermal sensor, light sensor and apart from biography
Sensor, the context detection module is in operating status always and is provided with journal file, for saving the detection of sensor
Data.
Wherein thermal sensor is radiated by the body temperature of detection human body to determine whether presence of people；Light sensor passes through
Detection light judges currently whether to be daytime or whether turn on light；Range sensor is sentenced by detecting the distance of surrounding objects
It is disconnected whether presence of people.
Further technical solution is that the wake-up module is provided with configuration file, for configuring the parameter of wake-up module.
Further technical solution is that the parameter of the wake-up module is confidence threshold value.
Further technical solution is that the comprehensive judgment module is provided with configuration file, is used for configuration rule parameter, institute
The detection data that the comprehensive context detection module obtained of comprehensive judgment module issues is stated, is judged whether by the parameter of regularity configured
Meet wake-up condition.
Further technical solution is that the parameter of regularity is configured by user.
Compared with prior art, the invention has the following beneficial effects: the languages provided by the invention surveyed based on environment measuring
Say wake-up system after detecting voice wake-up command, by detection ambient enviroment whether presence of people, if be daytime or
The method for whether having opened lamp reduces the false wake-up rate that voice wakes up system, improves user to decide whether to wake up smart machine
Experience.
Detailed description of the invention
Fig. 1 is the system diagram of Language awakening system of the invention.
Specific embodiment
The present invention is further detailed combined with specific embodiments below.
Embodiment 1
Implementing platform: 8.0 platform of MST848 Android；
Context detection module configuration: possess thermal sensor, light sensor and range sensor；
Wake-up module configuration: confidence threshold value is set as 80；
Comprehensive judgment module configuration: needing to be daytime or situation of turning on light, and needs presence of people, people and smart machine away from
From less than 3 meters；
Wake-up module receives the voice signal of smart machine admission, carries out the identification for waking up word.If waking up the confidence level of word
It has been greater than 80, has issued wake request to comprehensive judgment module.The detection data of comprehensive judgment module acquisition context detection module.If
The wake-up condition of configuration is met, then wake operation is carried out to smart machine；If not meeting the wake-up condition of configuration, assert
For the request for being false wake-up, it is not further processed.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferable embodiment, embodiment of the present invention are not limited by the above embodiments, it should be appreciated that those skilled in the art
Member can be designed that a lot of other modification and implementations, these modifications and implementations will fall in principle disclosed in the present application
Within scope and spirit.
