一种高速多功能语声处理系统的设计及实现方法
Design and Implementation of High-speed and Multi-function Speech Processing System
【摘要】 介绍一种由专用数字信号处理器(简称DSP)芯片和通用微机组成的多机主从处理系统。该系统集语声信号的输入和输出、时域和频域参数分析及三维动态语图绘制等多功能于一体,可实时实现数字信号处理多种复杂运算,比以住同类系统处理速度可提高2个数量级以上。并介绍了该系统的总体构成和主要功能软件的设计方法。
【Abstract】 This paper introduces a high -speed, mu1ti -function speech signa1 processing system. It uses theTexas Instruments TMS320C25 digital signal processor and general mieroeomputer, and combines manyfunctions for speech signal proeessing, such as speech input and output l the main time-domain and frequen-cy-domain parameters ana1ysis, and three-dimension dynamic spectrogram drawing, ete. It greatly raisesthe processing speed as eompared with such kind of system. Hardware and software aspects of the implemen-tation are described.
