语音信号亮度补偿技术研究

The Study of Lightness Equalizing for the Speech Signal

在语音信号处理系统中,系统回放语音通常发闷.本文通过分析语音信号衰减的原因,在不增加系统硬件成本的基础上,设计实现了语音信号高频补偿.实验证明,该技术大大地改善了语音回放质量,且切实可行,易于推广.

It is usually blurry to play back speech in the system of speech signal processing. The cause of speech signal attenuation is analyzed, the high frequency equalizing of speech signal is designed and carried out without additional cost of hardware. The experiments prove that the technique greatly improves the quality of speech playing back. It is feasible and prone to spread.
