随着科学技术的发展和老龄化进程的加快,为老年人及残障人提供性能优越的代步工具已成为整个社会重点关注的问题之一。智能轮椅是在普通轮椅的基础上融合语音识别技术的功能,通过语音对轮椅的各种运动进行控制,为广大用户提供了极大的便利。本文主要通过阐述语音识别的基本原理,设计智能轮椅的硬件电路、结构外形、软件电路以及软硬件调试,对智能轮椅语音识别与控制系统的设计进行详细研究,以期达到良好的识别效果。
With the development of science and technology and the acceleration of the aging process, it has become one of the key issues of concern for the entire society to provide superior means of transportation for the elderly and the handicapped. Intelligent wheelchair is based on the ordinary wheelchair speech recognition technology integration capabilities, through the voice of the wheelchair to control a variety of sports, for the majority of users with great convenience. This paper mainly studies the design of intelligent wheelchair speech recognition and control system by expatiating the basic principles of speech recognition, designing the hardware circuit, structure shape, software circuit and software and hardware of intelligent wheelchair, in order to achieve a good recognition effect.
