In this paper, using speech recognition technology and keyboard to control the importation of the integration of SCM in Sunplus SPCE061A achieve a voice on the electronic certification system password lock.This system is mainly posed of Sunplus SPCE061A SCM, MIC input circuit, voice output circuit, 4 4 keyboard, six Qiduan LED display and output control and FLASH memory ponents. System is the main function: the training, the speaker39。s personality characteristics and parameters Store, a speaker parameters database. In recognition, will be voice recognition and speaker parameters database matching, voice recognition and plete control of the keyboard, and activate or release of locks, the final pletion of the lock. System is relying on hardware and software to closely cooperate with the Sunplus SPCE061A SCM flexible control achieved. Voice entry due to the interference of external environment, it is possible errors, but through a number of training can make parison and identification of voice greatly improved.The system using a single kernel of Sunplus SPCE061A, the chip has ADC, DAC, timer / counter, RAM, FLASH, and other devices, coupled with appropriate external circuit and supporting Sunplus pany39。 suspension system to support 1 O interrupt vector And l4 from the system can be a clock, timer / counter, time benchmark generator, external interrupt, key wakeup call, Universal Asynchronous serial munication and software interruption interrupt source, Very suitable for realtime applications。nSPTM mand system also provides high puting speed of 16 16bit multiplication instructions and directives within the plot operation, the DSP for the application of additional features in a plex digital signal processing both Very convenient than the DSP chip for much cheaper.SPCE061A builtin 8channel 1 Obit A / D converter, which will be seven channels for analog signals (such as voltage signal) converted to digital signals, a channel used only for voice input, through the builtin automatic gain control amplifier The microphone channels (MICIN) input. Therefore, it can be directly given to the voice signal input channels, the pletion of 8 kHz voice signals in the collection, encoding and storage to offchip FLASH, simplifying the circuit design.Sunplus SPCE061A MCU with audio output of dualchannel 1 Obit D / A converters can plete user training, identification of various operations, such as the voice prompts. SPCE061A provide audio lose A way for the dualchannel DAC, in this manner, DAC1 and DAC2 conversion of analog current output signal passed AUD1 and AUD2pin output, enter the number of volume into the PDAC1 (write) (0 x7017) and P DAC2 (write) (0 x7016) unit.LED displays in each LED through 5 ~ 20mA current to achieve the normal brightness, and the IO I SPCEO61A output current up to 5 mA, do not have to drive circuit to reach normal brightness. In order to meet the reliability of systems design, driven by a tran
