MFCC parameters is main describes the spectrum envelope features, which is used to state the vacal track characterizatics, while ignoring the impact of pitchfrequency.
MFCC参数主要描述了表征声道特性的谱包络特征,而忽略了基音频率对它的影响。

The improved method based on fuzzy entropy, which analyzed and distilled the weight of speech duration, average magnitudes, pitchfrequency, formants and Mel-frequency cesptral coefficients.
If a singer hits a pitch that matches the frequency of one glass, the glass might absorb so much acoustic energy that it will shatter; the other glasses remain unaffected.
