语音识别技术在楼宇自控系统中的应用

Application of Speech Recognition Technology in Building Auto-Control System

随着语音识别技术的发展,孤立词、小词汇量的语音识别系统在日常生活中得到广泛应用,本文提出了一种基于DSP的孤立词实时语音识别系统,并将动态时间规整技术运用到识别算法中。根据楼宇控制系统的特点,结合BACnet网络协议,把系统设计成BACnet设备的一个嵌入式子系统,从而把语音识别应用到楼宇控制系统中。结合了系统硬件速度快、算法高效的特点,实现了对楼宇更加实时、方便的控制。

With the development of speech recognition technology, the isolate word and small vocabulary speech recognition has already been applied widely in daily lives. This paper introduces a isolate work real-time system which based on DSP, and uses the dynamic time warping technology to the recognition algorithm. According to the characteristic of building control system, combined with the BACnet protocol, the speech recognition system is designed as an embedded system of the BACnet device and can be applied in building control system. Due to the fast speed of hardware and high efficient of the algorithm, it realizes more timely and conveniently control on the intellegent building system.
