摘要

介绍了一种新颖的基于线性预测编码(LPC)处理算法的特征检测触觉声码器。该器件采用80386微处理器和TMS320C30浮点数字信号处理器。语音处理是实时的。声码器算法允许检测与声道的前三个共振峰以及基频相对应的频谱峰。这种LPC方法增强了声码器跟踪形成峰转换和基频的能力，并最大限度地减少了时空掩蔽。

Digital signal processor-based feature extraction vocoder for the deaf

An innovative feature detection tactile vocoder based on linear predictive coding (LPC) processing algorithms is described. The device utilizes the 80386 microprocessor and the TMS320C30 floating point digital signal processor. Speech processing is implemented in real-time. The vocoder algorithms allow the detection of spectral peaks corresponding to the first three formants of the vocal tract as well as fundamental frequency. This LPC approach enhances the ability of vocoders to track formant transitions and fundamental frequency, and it minimizes spatiotemporal masking.<>
