Composition, it is therefore an objective to rectify, adjust current direction.7805 voltage-stablizers have drawn 3 pins, and what the left side was drawn is its input
End, the right are its output ends, and what GND was represented is ground connection.Its input voltage cannot be greater than 36V, and the output voltage of permission is
4.8V-5.2V, maximum output electric current 1.5A, feature thermal overload protection, short-circuit protection, user are easy to use.Monolithic capacitor because
Capacity for it is small and frequency is small is used by us, and effect has two, one is energy storage exchanges, passes through the mistake of a charge and discharge
Journey discharges electric energy.The second is separated by direct communication, since monolithic capacitor is not a conducting body, the alternating current that it is passed through is that have rule
The steering of rule may be selected in circuit to embody both ends electrification and remaining component be in parallel, play the effect of bypass.Pass through
Alternating voltage 220V is converted into direct voltage 12V by a series of element, by the protection of bridge rectifier and voltage-stablizer and steady
It is fixed, whole system circuit is constituted,
As shown in figure 5, voice module RXD1, TXD1, the GND corresponding TXD for being connected to liquid crystal display, RXD, GND.RXD
Port is used to receive, and the port TXD is used to send, and the transmission pin of communicating pair voice module connects your reception of liquid crystal display and draws
Foot, the reception pin of voice module are connected to the transmission pin of liquid crystal display, are just able to achieve communication in this way.
Electrification reset as shown in Figure 6 is connected to reseting port by the resistance string of a capacitor and a 10k.
The internal logic figure of speech chip LD3320 chip since LD3320 can dynamically edit identification as shown in fig. 7, close
Keyword sentence list, its performance performance for other chips are more comprehensively more preferable, it is only necessary to which 51 single-chip microcontrollers are just
It can control whole system, reduce the cost in using, be equipped with 48 pins in chip, part pin used herein
MIC+ and MIC- is coupled with the positive and negative polarities of microphone, and GND is ground terminal, and there are also an ends to be connected to the 5V of power supply, makes it can be with
In power supply state.

System includes feature extraction, model of entering a higher school, speech model, the modules such as searching algorithm.Speech recognition system is a various modes
In conjunction with system, have difference to the method for identification voice, but basic principle is the same.The basic principle of speech recognition is as follows, to defeated
Enter voice spectrum analysis system to be pre-processed, by feature extraction, short cycle is known as frame, is extracted by frame unit composition characteristic
Speech recognition system input.The basic principle block diagram of speech recognition is as follows, makes pretreatment, frequency spectrum to the voice of input
The feature extraction Jing Guo system is analyzed, these short time intervals are referred to as frame, and the feature extraction as unit of frame is constituted speech recognition system
The input of system.In the LD3320 speech recognition process used herein arrived.
The interface module of LD3320 as shown in Figure 9, the module are gone here and there by single-chip microcontroller, speech chip, download circuit, LD3320
Mouth circuit composition.What single-chip microcontroller was selected is 51 single-chip microcontrollers, and the model of speech chip is LD3320.Single-chip microcontroller and host computer communication are logical
VCC/GND/RXD/TXD send instructions are crossed, wherein TXD2 meets single-chip microcontroller P3.1, and RXD2 connects the P3.0 mouth of single-chip microcontroller.
Working principle：
For a voice semanteme training system designed by patients with cerebral palsy, using in 51 single-chip microcontrollers
STC12C5A60S2, and adopted microphone according to the phonetic library of chip interior possessed with the speech chip of LD3320
The voice collected is converted to phonetic in library, compares with the phonetic inputted.There are two types of designed voice semantic system training
Mode, one is individual character mode, second is short sentence subpattern.When selection mode 1, word that patient occurs according to display screen
Start to read aloud, the collected voice messaging of institute, system can provide the correctness for judging that patient reads aloud in three seconds, display screen with
And computer display screen curtain will synchronize realization.Mode 2 is also with the principle as mode 1, and final system will be according to patient institute
There are the individual character read aloud and sentence statistical correction rate, given and prompted by sense light, and data feedback situation will be transmitted to far
Journey terminal.
In the present invention unless specifically defined or limited otherwise, fisrt feature is on or below second feature
It may include that the first and second features directly contact, also may include that the first and second features are not direct contacts but pass through it
Between other characterisation contact.Moreover, fisrt feature is on second feature, top and above include fisrt feature the
Right above two features and oblique upper, or first feature horizontal height is merely representative of higher than second feature.Fisrt feature is in the second spy
Under sign, lower section and fisrt feature included below be directly below and diagonally below the second feature, or be merely representative of fisrt feature level
Height is less than second feature.
