基于孤立词语音识别定位系统的研究与设计

Research and Design of Isolated Word Speech Recognition-based Positioning System

寻找物品是生活中常见而且耗时的事情,如能发明一种设备可以快速把随手放置的物品定位出来,必将大大方便人们的生活,犹如google对互联网的意义。本系统的设计独辟蹊径,结合了模拟电路技术和语音识别技术,利用语音作为输入触发信号,实现一种低成本的适用于家庭使用的快速物体定位系统。本系统在经典的孤立词语音识别技术的基础上,对进一步增大识别距离,提高抗噪能力及提高识别能力,提出一些很实用的技术与方法,并在本系统的实现中得到较好的应用。

Looking for the lost article is common in the daily life, yet very timeconsuming, if something can be designed to locate the article, our life will be more convenient. The system in the paper is of unique design which uses analog circuit technology and voice recognition technology and takes voice as an input trigger signal to produce the fast object positioning system with low cost and suitable for household use. The system, based on the classic speech recognition technology, puts forward practical techniques and methods to increase the recognition distance, improve the noise immunity and enhance the capability to identify. The system ensures good application if implemented.
