中文摘要：

针对当前语音信号处理大多在Matlab仿真,为了实现其在硬件系统的实时处理,设计了一个基于DSP/BIOS的语音信号处理系统。以SEED-DTK-VPM642构成硬件平台,采用DSP/BIOS实时操作系统为基础,将语音信号通过AIC23处理后,传到TMS320DM642实现语音信号的回声处理。实验结果表明,该系统通过改变相应参数,能实现语音信号的不同回声效果,实时性较好。

英文摘要：

Aiming at the current status of speech signal processing in Matlab simulation, in order to realize the real-time pro cessing of the hardware system, based on DSP/BIOS real-time operating system, a hardware platform is designed, which is composed of SEED-DTK VPM642. The speech signal is processed respectively by AIC23 and TMS320DM642. Experimental results show that the hardware system can realize the different echo effect of the speech signal by changing the corresponding parameters, and the real-time performance is good.
