Fig. 9 is a kind of scene application drawing provided by the present application；With reference to Fig. 9, the sound control method is applied to air-conditioning language
In sound control application scenarios, the phonetic controller is air-conditioning companion, and the pronunciation receiver is microphone.
Microphone receives the phonetic control command that user issues in some stationary sound source position and by phonetic control command
It is converted into electric signal and is sent to air-conditioning companion, air-conditioning companion receives electric signal and starts to work, and air-conditioning companion refers to according to voice control
It enables calculating and analyzes the knowledge that the current sound source position for obtaining user and microphone receive the phonetic control command of position in initial speech
Not rate, while microphone movement is controlled, microphone continues to the phonetic control command of user's sending in moving process and will
The corresponding electric signal of phonetic control command is sent to air-conditioning companion, and air-conditioning companion, which continues to calculate to analyze, obtains microphone in different languages
Sound receives the discrimination of the received phonetic control command in position, and compares different phonetic and receive the corresponding phonetic control command in position
Discrimination, obtain maximum discrimination score, the phonetic incepting position of the corresponding microphone of maximum discrimination score is user described solid
When determining sound source position sending phonetic control command, the first phonetic incepting position of microphone, i.e. best voice receive position.
In order to reduce user when the same fixed locations of different periods carry out voice control to air-conditioning, air-conditioning companion is repeated
The the first phonetic incepting position for calculating analysis microphone, when causing the expense of calculation process excessive, and being needed due to calculation processing
Between, cause voice control to be delayed, sensitivity is inadequate, and the present processes are that different sound source positions (such as doorway, sofa) are right
The the first phonetic incepting position obtained for the first time answered stores, and carries out in identical sound source position to air-conditioning when user's next moment
When voice control, air-conditioning companion, which directly sets from history sound source received bit, calls corresponding first phonetic incepting position as working as in table
Preceding first phonetic incepting position come move microphone adjustment microphone phonetic incepting position, efficiently solve and recalculate place
The problem of managing bring control delay, in addition, the voice typical time due to user is all shorter, also effectively makes air-conditioning companion
By voice control air-conditioning much sooner, efficiently receive user instruction, keep voice control sensitiveer.
During the work time due to air-conditioning, noise generation is had, and air-conditioning is under different working modes, different temperatures,
The noise level of generation is also different, therefore the interference of noise will affect reception of the microphone to user speech control instruction.This
Apply for that another improved place is exactly to calculate command range between microphone and air-conditioning and air-conditioning in current operation mode
Noise information microphone is adjusted to the second phonetic incepting position in conjunction with the first current phonetic incepting position of microphone, the
Two phonetic incepting positions be the first phonetic incepting position is adjusted according to the command range and the noise information so that
The position of the ratio between noise jamming rate and discrimination within a preset range, makes between noise jamming and the discrimination of phonetic control command
Reach a balance, further makes to reduce noise jamming of the air conditioner noises to microphone.
With reference to Fig. 9, air-conditioning companion includes motor, guide rail, and air-conditioning companion is by motor control microphone on the guide rail
Circumferentially path can 360 degree of movements.
Sound control method and device provided by the present application lead to according to the phonetic control command that same position sound source issues
Cross air-conditioning companion control microphone be moved to received phonetic control command discrimination be maximum discrimination score the first voice connect
Position is received, the accuracy rate of phonetic incepting in voice control, identification is improved.
The sound control method of the application also stores the sound source position and corresponding first voice of each different location sound source
Position is received, when the range difference of current sound source position and history sound source position is within the scope of pre-determined distance difference, directly by Mike
Wind, which is moved to corresponding the first phonetic incepting of history position, can accurately receive phonetic order, not need to be repeated analysis meter
It calculates, saves and calculate the time, keep voice control more timely, convenient, sensitive.
The sound control method of the application also adds analysis to the noise of controlled device and to microphone and controlled
The command range of equipment considers, comprehensively control distance and noise analysis are by the first phonetic incepting fine position to the second phonetic incepting
Position reduces the interference of noise, keeps the accuracy rate of phonetic incepting, identification higher, further increases the efficient of voice control
Property.
In addition the sound control method and device of the application may not only be applied to air-conditioning, for other families such as television set, lamp
Electricity is equally applicable, and is kept big data intelligent control more perfect, is greatly facilitated people's lives.
