基于DSP的语音识别在智能楼宇系统中的应用

随着DSP技术的发展,中小词汇量连续语音的实时识别已经被广泛应用到日常生活中,本文提出了一种基于TMS320VC5410的小词汇量的语音识别实时系统,对以TMS320VC5410为核心的系统硬件设计进行了研究,阐述了系统的结构。文章分析了系统的工作过程,引用已有的算法进行软件系统设计,软件模块包括预处理、端点检测、特征提取、模式匹配等。最后把此系统应用到智能楼宇系统中去,实现了对智能楼宇更加及时、方便的控制。

Application of Speech Recognition Based on DSP in Intelligent Building System

With the development of DSP technology, the small vocabulary continual real - time speech recognition has already been applied widely in daily lives. This paper introduces a small vocabulary real -time system which is based on TMS320VC5410, and also introduces how to design the system, in which TMS320VC5410 is used as its core circuit.we apply the existing arithmetic to design the soft system, The soft module inculd per - emphasis,frameblocking, windowing, drawing the characteristic of speech signal, pattern matching. At last we applies this speech recognition to intelligent building system. It realizes more timely and conveniently control on the intelligent building system .
