Feedback signal is received and parsed through to generate infrared signal, and infrared signal is sent to electrical equipment and is set with controlling the electric appliance
It is standby.
Specifically, if from the default language in the target voice feature and memory module 16 obtained in feature extraction unit 142
When the ratio of sound Characteristic Contrast is greater than or equal to the phonetic feature matching threshold set in threshold setting unit 141, the matching analysis
Unit 143 includes the specifying information of infrared signal to be launched to 15 positive feedback signal of infrared transmitter, in the positive feedback signal,
That is coding corresponding to infrared signal, so as to issue different infrared signals by different phonetic orders, to different electricity
The control of device or control to identical electric appliance different function.Infrared transmitter 15 receives and parses through feedback signal to generate infrared letter
Number, and infrared signal is sent to electrical equipment to control the electrical equipment.If the mesh obtained from feature extraction unit 142
The ratio of default phonetic feature comparison in mark phonetic feature and memory module 16 is less than the language set in threshold setting unit 141
When sound characteristic matching threshold value, the matching analysis unit 143 issues infrared conversion negative-feedback signal to infrared transmitter 15, or not to red
External transmitter 15, which issues feedback signal namely infrared transmitter 15, will not issue infrared signal.
For example, it is assumed that the default phonetic feature in memory module 16 is the phase of the directive statement " please open fan " of user A
Phonetic feature is closed, if the first acquisition module 11 collects " opening fan " in user A or user B, " please open fan " or " opens
The associated speech data of the directive statements such as fan ", voice data of the preprocessing module 13 to the directive statement of user A or user B
Removal of impurities pretreatment is carried out, obtains the target speech data of directive statement, the feature extraction unit 142 of speech recognition module 14 is to mesh
It marks phrase data and carries out speech feature extraction, the matching analysis unit 143 is by the A obtained from feature extraction unit 142 or user B
The related objective phonetic feature and memory module 16 of directive statements such as " open fan ", " fan please be open " or " opening fan " in
User A directive statement " fan please be open " preset phonetic feature comparison, if its comparison ratio set more than or equal to threshold value
When setting the phonetic feature matching threshold set in unit 141, if the threshold value is to obtain in 90% namely feature extraction unit 142
A or user B the related objective phonetic feature of directive statements such as " open fan ", " fan please be open " or " opening fan " with deposit
When storing up the ratio of the default phonetic feature of directive statement " fan please be open " of the user A in module 16 more than or equal to 90%, recognize
To be successful match, then after the matching analysis unit 143 issues infrared conversion positive feedback signal to infrared transmitter 15, generates and correspond to
Infrared signal, and by the infrared signal control fan open.Otherwise the matching analysis unit 143 is issued to infrared transmitter 15
Infrared conversion negative-feedback signal, or infrared conversion feedback signal namely infrared transmitter 15 are not issued not to infrared transmitter 15
Movement.

And parse the matching analysis unit 143 sending feedback signal, and control based on the feedback signal infrared generating unit 153 generate it is infrared
Signal, then infrared signal is given to the electrical equipment with infrared induction by infrared emission unit, to realize to the electrical equipment
Control.
Specifically, it is assumed that positive feedback signal is binary coding such as " 0101 ", " 0100 ", wherein " 0101 " and the infrared letter of A
Number mapping, the A class infrared signal control fan " yaw "；" 0100 " and B infrared signal map, which controls fan
" opening fan "
When control unit 151 receive be the matching analysis unit 143 positive feedback signal, then parse the positive feedback signal
It obtains binary coding " 0100 ", then control the corresponding generation of infrared generating unit 153 is B infrared signal, passes through infrared emission
Unit 155 emits B infrared signal to electrical equipment, and control fan executes " opening fan " movement, opens fan.
When what control unit 151 received is the negative-feedback signal of the matching analysis unit 143 or does not receive the matching analysis list
When the feedback signal of member 143, then infrared generating unit 153 is failure to actuate.
