摘要

本文介绍了一种用于视觉和听觉障碍人士将语音信息转换为盲文输出的原型装置的实现。本交互装置采用HM2007集成电路。输入是通过接收语音信号和识别数字来实现的。一旦语音数字被识别，DSP处理器将发送相应的ASCII码到PIC与必要的编码信息。该系统的输出是一个盲文显示器。PIC微控制器从DSP获取编码输入，对其进行解码，并通过螺线管驱动器发送适当的可识别盲文单元。整个系统以泰米尔语Thirukural的接收数字作为语音信号来实现，并对输出的数字进行测试，泰米尔语Thirukural对每个字母进行延迟时间的压印。

Conversion of speech to Braille: Interaction device for visual and hearing impaired

This research paper describes the implementation of a prototype device for both Visual and Hearing impaired persons get information from Speech converting to Braille output. For this interaction device HM2007 IC is used. The input is by receiving the speech signal and to recognize the digits. Once the spoken digit has been recognized, the DSP processer will send the corresponding ASCII code to the PIC with necessary encoded information. The output of this system is a Braille Display. The PIC microcontroller takes the encoded input from the DSP, decodes it and sends the appropriate recognized Braille cell trough the Solenoid Driver. The entire system is implemented with receiving digits of the Tamil Thirukural as speech signal and the output of the digits is tested with the Tamil Thirukural embossing every letter with delay time.
