Description of drawings
But Fig. 1 is the principle schematic of television set first embodiment of speech controling switch;
But Fig. 2 is the principle schematic of television set second embodiment of speech controling switch.
Embodiment
But the television set of speech controling switch provided by the utility model is by gathering and identify user's phonetic control command, the switching of control television set.But be described below in conjunction with the television set of accompanying drawing to speech controling switch described in the utility model.
But the principle schematic of television set first embodiment of speech controling switch as shown in Figure 1, television set comprise voice controller 10, TV set power 104 and the governor circuit 201 that connects successively, and the battery 105 that is connected with voice controller 10.
Wherein, described governor circuit 201 is used for the audio frequency and video display system of control television set.Described audio frequency and video display system comprises: tuner, the video decoding unit that is connected with tuner, audio decoding unit, and the display screen that is connected with video decoding unit and loud speaker that is connected with audio decoding unit etc., said apparatus belongs to the television set known technology, repeats no more.
Wherein, voice collecting unit 101 is used for user's phonetic control command information and coding are processed.The function of voice collecting unit 101 is by comprising that model is the circuit realization of TLV320AIC3104 chip.The monophony simulated audio signal that voice collecting unit 101 gathers is digital signal by the A/D modular converter code conversion of TLV320AIC3104 chip internal.
Wherein, the normalization module is used for audio frequency is carried out normalized, to eliminate the height difference of different channel audio sound.According to expression formula y (n)=x (n)/max (| x (n) |), wherein, the audio sound after y (n) the expression normalized, x (n) represents former audio sound.The function of described normalization module is by comprising that model is the circuit realization of TMS320C549 integrated chip.
The preemphasis processing module is used for promoting the HFS of voice data.Because voice data can lose the part radio-frequency component through after decoding, process the lifting HFS by preemphasis, realize that voice data keeps smooth at frequency band.Preemphasis is processed by the digital filter of single order and is realized, that is: H (z)=1-μ z
-1
Divide the frame processing module to be used for dividing frame to process to voice data.Voice data has time-varying characteristics, but enough (for example 10ms～30ms), its characteristic remains unchanged substantially, and is namely relatively stable in short time at one section.Therefore divide frame to process every frame duration 20ms to decoded voice data.Can to seamlessly transit in order making between frame and the frame, to keep its continuity, the present embodiment adopts the method for overlapping segmentation, and namely the frame head of the postamble of each frame and next frame is overlapping, and the ratio that frame moves with frame length generally is taken as 1/3～1/2.The function of described minute frame processing module is by comprising that model is the circuit realization of 74HC393 integrated chip.
The windowing process module is used for eliminating the discontinuity of the adjacent frame head and the tail of frequency division voice data.It is because minute frame is processed the discontinuity of caused adjacent frame head and the tail in order to eliminate mutually that each frame voice data is carried out windowing process.Hamming (Hamming) window is adopted in described windowing process:
0≤n≤N-1。As sampling period T
s=1/f
sOne regularly, and the pass between length of window N and the frequency resolution Δ f is:
As sampling period T
sDuring for definite value, along with the variation of the window size N that selects, frequency Δ f constantly changes.If window selection is too small, frequency resolution can reduce; If window selection is excessive, frequency resolution can improve and just reduction of temporal resolution.The function of described windowing process module is by comprising that model is the circuit realization of SN54HC151J integrated chip.
Described control unit 103 comprises memory module and sound identification module.
Wherein, memory is used for storing control information, and described control information and phonetic control command information are complementary.
Sound identification module identifies control command corresponding to phonetic control command information that receives, and exports accordingly control information for the control information of storing according to memory module and the matching relationship of phonetic control command information.The function of sound identification module can be the circuit realization of LD3320 by comprising model.
Need to prove, also comprise an auxiliary power supply module (not shown) in the TV set power 104, be connected with control unit 103, be used for providing the power supply of 5V low-power consumption standby to control unit 103.Thus, when television set is closed, battery 105 is only arranged to voice collecting unit 101 and Audio Processing Unit 102 power supplies, and the auxiliary power supply module is powered to control unit 103 low-power consumption.And the larger governor circuit 201 of power consumption is in closed condition, therefore, when television set is closed, can realize effectively reducing energy consumption.
Assign the phonetic control command of start as the user after, voice controller 10 gathers user's phonetic control command information, identifies rear output control information to TV set power 104, to governor circuit 201 power supplies, realizes television boot-strap by TV set power 104.Simultaneously, because battery 105 is connected with TV set power 104, behind the television boot-strap, charged to battery 105 by TV set power 104.After guaranteeing that television set shuts down again, battery 105 is to voice collecting unit 101 and Audio Processing Unit 102 power supplies.
Accordingly, assign the phonetic control command of shutdown as the user after, voice controller 10 gathers users' phonetic control command information, identifies rear output control information to TV set power 104, stops to realize the television set shutdown to governor circuit 201 power supplies.After the shutdown, voice collecting unit 101 and Audio Processing Unit 102 be by battery 105 power supply, with the phonetic control command of the start of monitoring users.
As shown in Figure 2, but the principle schematic of having shown television set second embodiment of speech controling switch, the difference of the second embodiment and the first embodiment is: in the present embodiment, do not comprise described auxiliary power supply module in the TV set power 104, described voice collecting unit 101, Audio Processing Unit 102 are connected with control unit and all are connected with battery 105.When television set is closed, powered to said units by battery 105.Can further reduce power consumption thus.Assign the phonetic control command of start as the user after, the control information that TV set power 104 reception control units 103 are sent to governor circuit 201 power supplies, realizes television boot-strap.Charge to battery 105 simultaneously.
The above only is preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included in guarantor's loud speaker of the present utility model and protect within the scope.
