| 摘 要： | 为了提高语音识别系统的可靠性和高效率性，利用线性预测倒谱（LPCC）和动态时问规整技术（DTW）设计了一种语音识别系统．系统以TI公司的TMS320VC5402DSP芯片为控制核心，以汉语言的短命令为识别对象，实现特定孤立词语言识别功能．系统设计了串行通讯接口，更好地利用计算机对其控制．同时系统能进行语音指令的识别并做出相应的应答．该系统适合应用在一些智能控制领域，且结构简单，功能稳定．

| Abstract: | Due to improve the reliability and efficiency of the intelligent voice recognition system,an intelligent voice recognition system is designed by using the LPCC and the DTW theory.The system takes the TMS320VC5402 as the central processor and use the short Chinese orders as objects of recognition voice traits to realize the function of isolated words recognition.A serial communicate interface is designed to make the system adapted to concentrate control.This system can release the recognition of speech instruction and can also reply it which can be used in many intelligent control areas.The structure of the system is more simple and stable. |
