Amount and the instruction of corresponding drive control.
3rd embodiment as the application, it is also proposed that a kind of LED illumination sound control method, implement based on above-mentioned first
The LED illumination speech control system that example is proposed, as shown in figure 5, including：
Step S1：User terminal receives the voice messaging of user；
Wherein, as shown in fig. 6, step S1：The voice messaging that user terminal receives user specifically includes：
Step S101：Voice controller sends detection instruction to user terminal；
Step S102：Whether detection user's application starts, and if it is continues, otherwise repeats step S102；
Wherein, the data of application operation in the packet that voice controller detects return be present, be then judged as user
Using startup, now, the voice collector closed in voice controller, to avoid the voice messaging crosstalk gathered simultaneously.
Step S103：Begin listening for the voice collector of user terminal；
Speech data is stored into the speech memory of user terminal by the voice collector at monitoring users end, can be with
Store into RAM or ROM；And it is further, it can also be preserved in time in user terminal power down using nonvolatile storage
Voice messaging, and continue when user terminal restores electricity to voice controller transmission voice messaging.
Step S104：Judge whether voice collector collects voice messaging, if it is continue, otherwise repeat step
Rapid S104；
After performing step S104 and collecting voice messaging, also go to following step and the integrality of voice is sentenced
It is disconnected.
Step S1041：8 discriminative informations for stealing frame bit of cumulative binary bit sequence frame；
Step S1042：Cumulative discriminative information result is compared with threshold value；It is judged as effective language if threshold value is more than
Sound frame, step S1043 is performed, is not otherwise effective speech frame, perform step S1044；
Step S1043：The correct criterion of speech frame is used as using the first bit error rate threshold；
Step S1044：The correct criterion of speech frame is used as using the second bit error rate threshold.
Step S105：Voice messaging is sent to speech memory and stored.
The purpose of storage is the accuracy for ensureing voice messaging, prevents instruction from causing instruction not given birth to because of transmission fault
Into success, also to ensure that the validity of instruction, will not cause maloperation, for being stored in phonetic storage because of overdue instruction
Voice messaging in device enters line delay deletion, for example, when voice messaging is sent to speech memory, starts timing, timing
After 10ms, if voice controller does not receive this voice messaging, the voice messaging is deleted from speech memory, voice
Controller is not made a response, it is necessary in the case of can also by user application remind user send voice messaging again.
Step S2：Voice messaging is sent to voice controller by user terminal；
Wherein, as shown in fig. 7, voice messaging is sent to voice controller by user terminal is specially：
Step S201：Voice messaging is converted into data signal；
Step S202：Data signal is sent to first data transmission interface；
Step S203：Data signal is reduced to voice messaging by voice controller；
Step S204：Send to memory and stored, and send to recognition processor；
Step S205：Recognition processor pre-processes to voice messaging.
Pretreatment specifically includes removing other based process processes such as noise.
Step S3：The voice messaging that voice controller identification receives；
Wherein, as shown in figure 8, the voice messaging that voice controller identification receives is specially：
Step S301：Pretreated voice is subjected to end-point detection；
Step S302：Extract the characteristic vector of voice messaging；
Step S303：Characteristic vector is compared with preset sound instruction collection；
Sound instruction collection corresponds with command content, such as lights instruction, extinguishes instruction, flicker and delayed startup etc..
Comparison process can be carried out by the way of traversal, can also be compared by the way of index, to accelerate comparison time.
Step S304：Judge whether to draw corresponding command content, if it is perform step S4, otherwise sent out to user terminal
Send fault alarm.
Specifically, fault alarm information is " unidentified go out the instruction " or " phonetic order mistake ", and prompts user's weight
Newly send phonetic order information.Now user can be normal instructions to the instruction of user's application response, then now user applies
Download can be compared from server by network and changes the corresponding command information of voice messaging, at the same by the voice messaging and
Corresponding command information is sent to voice controller and stored.
Step S4：Voice controller is according to the control instruction control LED drive circuit corresponding to voice messaging.
Using above-mentioned technical proposal, due to being provided with voice controller, the voice that user is gathered by voice collector is believed
Breath, and voice messaging is converted to by control instruction by recognition processor, then LED illumination System is controlled by control processor,
Allow to arbitrarily control LED illumination System, meet to be precisely controlled illuminator.
Embodiments of the present invention are explained in detail above in association with accompanying drawing, but the invention is not restricted to described implementation
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen within protection scope of the present invention.
