【摘要】：在过去的三十年中,图形用户界面作为人与机器之间的通信接口取得了很大的进展,但使用图形用户界面需要用到视觉与手的操作,对于盲人以及肢体残疾等这一特殊群体来说存在着诸多的不方便之处。而在智能家居的交互式控制中应用语音用户界面,能够充分地利用了语音这一人类进行信息交流最直接、最方便和最有效的工具来进行人与机器之间的通信,将能大大方便盲人的独立生活。本论文的最终研究目标是实现一个基于语音识别技术的盲人家居辅助系统。采用ARM嵌入式系统技术和语音识别技术,以及软件工程结构化设计方法。本论文主要完成了以下工作:1、功能需求分析,从用户角度出发,分析用户对本系统的功能需求;2、关键技术研究,包括提高语音识别技术准确率以及如何在嵌入式系统中使用语音合成技术;3、系统的硬件电路设计,设计内容包括:主控制电路设计、语音识别电路设计、GSM通信电路设计、开关控制电路设计以及电源电路设计;4、系统的软件设计,设计内容包括:主程序设计、语音识别模块软件设计以及GSM通信模块软件设计。本系统将能够在更大程度辅助盲人的生活,给盲人的独立家居生活带来方便。本论文具有非常实用的应用价值,并且对于今后开发类似产品也具有一定的参考价值。
[Abstract]:In the past three decades, the graphical user interface has made great progress as a communication interface between human and machine, but the use of graphical user interface requires the operation of vision and hand. There are many inconveniences for this special group, such as the blind and the physical disability. The application of voice user interface in the interactive control of smart home can make full use of voice, which is the most direct, convenient and effective tool to communicate between human and machine. It will greatly facilitate the independent life of blind people. The final research goal of this thesis is to realize a blind home assistant system based on speech recognition technology. ARM embedded system technology and speech recognition technology, as well as software engineering structured design method. This paper mainly completed the following work: 1, functional requirements analysis, from the perspective of users, analysis of the user's functional requirements of the system 2, key technology research, It includes how to improve the accuracy of speech recognition technology and how to use speech synthesis technology in embedded system. The hardware circuit design of the system includes main control circuit design, speech recognition circuit design and GSM communication circuit design. Switch control circuit design and power supply circuit design. The software design of the system includes: main program design, speech recognition module software design and GSM communication module software design. The system will be able to assist the blind to a greater extent and bring convenience to the independent home life of the blind. This paper has very practical application value, and also has certain reference value for the development of similar products in the future.
