基于ARM的皮肤听声系统的设计

Skin-hearing systems designs based on ARM

为了提高皮肤听声器的性能,提出了一种基于ARM(先进的精简指令计算机处理器)的嵌入式皮肤听声系统设计方案,包括硬件设计、软件设计与一些滤波算法的实现。该系统在原来皮肤听声器的模拟电路中加入数字电路的设计,将嵌入式技术、皮肤听声技术与语音识别技术相融合,不仅可以让听觉障碍者通过皮肤感知到声音,还可以把说话人的声音信号以文本形式在屏幕上加以显示。实验结果表明,该系统提高了皮肤听声器的识别率,有效地解决了部分简单语音辨析难的问题。

In order to improve skin-hearing aid compact effect,amethod to embedded skin-hearing systems designs byARM（advanced RISC machines） is proposed,which includes the design of hardware,software and digital filter implement of algorithm.The systems adds digital circuits to primary circuits,which contains skin-hearing technology,speech recognition technology and the embedded technology. The embedded skin-hearing systems not only can make deaf patient get the feeling of voice through skin,but also achieve speech recognition.Experimental results show that the systemto improve recognition rate,effectively solve the problems of simple voice analysis.
