Wherein keyword extraction has used speech processes special chip LD3320 with mating, microcontroller uses STC10L08XE single-chip microcomputer, the P0 mouth of STC10L08XE single-chip microcomputer connects the data port of LD3320, the P3.6 of STC10L08XE single-chip microcomputer, P3.7 mouth connects the 42nd and the 45th pin of LD3320 respectively, the read-write of control LD3320.
In the present embodiment, STC10L08XE single-chip microcomputer is connected by standard UART serial ports with GPRS wireless transmitter module, so the P3.0 mouth of STC10L08XE single-chip microcomputer connects the TXD of GPRS module, P3.1 mouth connects the RXD of GPRS module.
As shown in Figure 4, field speech voice signal accesses 13 and 14 pins of LD3320 after amplification filtering, 39 of data-carrier store access LD3320, 40, 41 pins, microcontroller STC10L08XE connects 34 to 38 pins and the 42nd and the 45th pin of LD3320, Fig. 4 is the fundamental diagram of LD3320, LD3320 is integrated with voice recognition processor and some peripheral circuits, comprise AD, DA fills parallel operation, microphone interface, voice output interface etc., this chip does not need to write complicated voice recognition algorithm, can Auto-matching sound recognition, concrete control flow is, LD_reset () function is inputted to LD3320 by STC10L08XE single-chip microcomputer, make chip reset, need speech recognition initialization afterwards, and voice keyword write recognized list.
Data transmission interface due to GPRS module is standard asynchronous communication serial port RS232, therefore the design needs design standards RS232 interface circuit, as shown in Figure 5, microcontroller STC10L08XE single-chip microcomputer P3.0 is connected respectively by two pins, P3.1 pin, STC10L08X single-chip microcomputer interrupts sending information to GPRS module by serial ports.
System program mainly comprises master routine and Interrupt Subroutine, and as shown in Figure 6, key step is as follows:
Step one: send instruction LD_init () and make the initialization of LD3320 voice recognition chip;
Step 2: serial ports interrupts initialization, sends instruction ES=1, is set to serial ports and interrupts;
Step 3: speech recognition contrasts, and enters Speech comparison subroutine, contrasts the voice keyword recorded in advance;
Step 4: send recognition result to serial ports.
In step 3, the contrast of voice keyword is if the same reported to the police, if do not mated, then returns speech recognition, from newly judging that whether next voice is identical with the voice phonetic storage chip.
Adopt speech recognition technology to carry out automatic alarm and there is following advantage:
1) by voice recognition chip, automatically voice keyword is identified.
2) autonomous system is adopted, convenient interconnected with existing warning system.
3) safety more timely than existing manual alarm device.
4) discrimination is high.
