频谱斜率 meaning in English

spectrum slope

Moreover in speech enhancement , especially in reducing the pulse noise , morphological algorithm has its unique advantage . particularly morphological filter may maintain the preferable accurate of the speech signal in speech waveform , and which produces little impairment to the formant of speech . so the spectrum structure of the speech is retained well , and the quality of the speech will not be reduced
特别是，在时域波形分析中，形态学滤波增强较小波去噪更好地保持语音信号的细节；在频域分析中，形态学滤波对语音信号的基音频率、频谱斜率、共振峰等语音特征的影响很小，因而能够较好的保留语音信号的频谱结构，使语音品质不致降低。
