【摘要】 针对人们对导航系统人机界面越来越高的要求,介绍了基于IIS总线的数字音频系统在车载导航系统中的应用。该系统利用线性预测倒谱系数(LPCC)作为语音信号的特征参数,运用VQ矢量量化技术实现特定人的孤立词识别,通过特定人孤立词识别算法,将语音输入转化成命令,可以实现更友好的人机交互。更多还原

【Abstract】 Navigation system for the people has more and more human-machine interface requirements.This paper describes the IIS bus-based digital audio system in car navigation system applications.The system uses linear prediction cepstral coefficients(LPCC) as feature parameters of speech signals,used VQ vector quantization techniques to achieve specific human isolated word recognition,and isolated word recognition by specific human algorithm.By put the voice into a command,more friendly human-computer interaction can achieved.更多还原
