基于ARM的嵌入式语音识别系统研究

The Research of Embedded Speech Recognition System Based on ARM

在分析语音识别原理的基础上,设计了一个基于ARM9和嵌入式Linux的嵌入式语音识别系统。采用动态时间归整(DTW)算法对语音信号进行特征参数序列比较并识别出结果。采用S3C2410微处理器和嵌入式Linux操作系统,将交叉编译后的语音识别C语言程序编译进嵌入式Linux操作系统的文件系统,实现语音识别系统的功能。

A embedded speech recognition system based on ARM9 and embedded linux was designed after analyzing speech recognition theory.The speech recognition system adopts dynamic time warping （DTW）algorism to compare the characteristic parameters of speech signal with each other and recognize the result of speech signal.To achieve the function of speech recognition system,the $3C2410 microprocessor and embedded linux OS is adopted,then compile the cross-compiled C programme into file system of embedded linux OS.
