摘要
计算机技术的飞速发展带动语音识别技术不断取得突破,功能日渐强大的语音控制系统正逐渐应用于实际生活中。LD3320是一款语音识别专用芯片,响应快,识别率高,系统结合STC11L08XE单片机及外围电路和n RF24L01无线传输芯片进行了声控灯系统总体结构及各个模块的硬件选型和程序编写,并基于非特定人完成了对声控灯系统功能的静态测试,识别率接近95%,实验效果理想。该嵌入式系统体积小、功耗低、性能稳定、实时性好,在生产和生活中具有较高实用价值。
Since the break-though of voice recognition technology is droved by rapid development of computer technology, the powerful voice control system is gradually applied in real life. LD3320 is a dedicated chip for voice recognition,with fast re-sponse and high recognition rate characteristics. The overall structure design of voice-controlled light system combines STC11L08XE,peripheral circuit and wireless transmission chip nRF24L01,in which hardware selection and software program-ming of each module are proceeded. The static test of the functions for voice- controlled light system based on person-indepen-dent was implemented,the recognition rate is approach to 95% and the experimental effect is satisfying. The proposed embed-ded system has the characteristics of small size,low power dissipation,stable performance and good real-time performance. It has high practical value in manufacture and living.
