| 摘 要： | 针对耳聋患者的听阈曲线与正常人之间的区别,提出一种在频域内实现语音响度补偿的新算法,即频率细分响度补偿法,就是对每一帧语音信号频谱变换后,对频谱所含的每个频率点进行相应的增益补偿,并用TMS320VC5509A DSP芯片实现。

| Abstract: | According to the difference of hearing threshold curve between deaf and normal people, the study offers a new algorithm to realize the voice loudness compensation in the frequency domain, that is, the frequency of subdivision loudness compensation method. Corresponding gain compensation will be made for each frequency point in the frequency spectrum after the transformation of each frame in the speech signal spectrum, which is realized by the TMS320VC5509A DSP Core. |
