为了解决皮肤听声器辨析语音的问题,提出了将时频分布应用于皮肤听声器,增加皮肤听声器的通道教量,从而使其能够达到辨析语音的要求;时频分布克服了时域分析和频域分析的不足,能够比较直观、合理地描述语音信号在时间一频率域上的能量分布情况及信号频率随时问变化的关系;最后,通过4通道皮肤听声器的实验,皮肤感受到了简单汉语语音的区别,从而验证了该方法是可行的.%To solve the problems of voice-analysis in skin-hearing, time-frequency distribution and increasing the number of channels in Skin-hearing Aid Compact is proposed to meet the requirements of analysis of voice.The shortcomings of the time-domain analysis and frequency domain analysis is overcome by time-frequency distribution, which can be intuitive and reasonable description the signal of the energy distribution and the signal frequency with time-varying relationship in time-frequency domain.Finally, the difference of simple Chinese phonetics is felt by the skin through the 4-channel Skin-hearing Aid Compact experiment, which verify that the method is feasible.
