摘要
运用软硬件协同设计,在DE2-70开发板上实现了一个基于SoPC的实时说话人识别控制器,控制器有很好的实时性和良好的识别性能。控制器的语音特征参数采用线性预测倒谱系数(LPCC),匹配算法采用动态时间规整算法(DTW)。
A real-time speaker recognition controller based on SoPC using DE2-70 development board is discussed in this paper. Since the controller is designed based on hardware and software co-design methodology, it is excellent in real-time processing and good in performance. LPCC is selected as speech features, and dynamic time warping （DTW） algorithm as matching algorithm in this design.
