Firstly,we particularly explained the algorithmic of themusic recognition.Then,we made a study of the music characteristic and the musicrecognition methods.As for the burrs of the music signal,we put forward a curveplastic method to eliminate the burrs.Considering the difficulties of detecting thepoint of the music speech,we made use of the multi-frequency energy curve to detectthe end-point of the music signal with the crossing zeros rate.As for thedisadvantages of the large operation and influence of the formant,we improved theAMDF theory with the linear prediction algorithmic to detect the error.In order toobtain the characteristic parameter of the music signal,wo calculate the MFCCparameter to obtain the template and the pending signal characteristic parameter.Inorder to improve the rate of the recognition,considering the disadvantages of theDTW algorithmic,we find a new method to improved the DTW algorithmic bybroadening the point of the music signal and made simulation experimentation;As forthe disadvantages of the contraposition grade to the pitch,cadent and sing name,wefind a method to dynaic adjust the results of the recognition to improve the accuracyof the grade.

According to simple computation, good anti-noise ability and low precision of Katz algorithm and complex computation and good precision of box-counting dimension and correlation dimension, an Improvement fractal algorithm Based on Wave is presented and analyzed through the fractal Brown curve and noisy speech according to the characteristic of the box dimension and Katz dimension.

摘要該文針對目前的分維計算方法——盒維、關(guān)聯(lián)維等精度雖高欧美丝袜A∨在线一区二区三区，但計算復(fù)雜久操视频福利在线，Katz維計算簡單、抗噪性能好加勒比官网中文在线、但精度不高的現(xiàn)狀日韩精品理论片在线观看，提出了一種改進的基于波形的算法——IBW-FD，分析了對分形布朗曲線国产麻豆综合在线视频、含噪語音(高斯白噪聲欧美黑人大屌视频，三種非平穩(wěn)噪聲)的性能。

Methods 22 parients(35 ears)had been tested in three noises, including white noise,speech noiseand babble noise.BN was recorded when 8～12 persons were talking at same time.The monosyllabic phonetic balance word list was made by Shen Ye in 1983 and every list includs twenty-five words,Meantime ,the effect to speech discrimination score curve was tested in different signal to noise ratio.
