说明：  利用极值分布weibull威布尔分布，先对其进行参数估计，然后判断可靠性，亲测可用(Using the Weibull Weibull distribution of extreme value distribution, the parameters of Weibull distribution are estimated first, and then the reliability is judged, which can be used in pro test)

DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法。用于孤立词识别，DTW算法与HMM算法在训练阶段需要提供大量的语音数据，通过反复计算才能得到模型参数，而DTW算法的训练中几乎不需要额外的计算。所以在孤立词语音识别中，DTW算法仍然得到广泛的应用。 (DTW (Dynamic Time Warping, dynamic time warping) algorithm based on dynamic programming (DP) ideas, sounds of varying lengths to solve the template matching problem, is speech recognition appeared earlier, more classic kind of algorithm. For isolated word recognition, DTW algorithm and HMM algorithm in the training phase need to provide a large number of voice data, obtained by repeated calculations to model parameters, while the DTW algorithm is almost no additional training calculations. Therefore, in isolated word speech recognition, DTW algorithm is still widely used.)

Cours Roc Curve tres utiles Rappels sur la courbe ROC (Receiver Operating Characteristic Curve) Supposons qu une population soit répartie en deux classes notées respectivement 1 et 0. Mais, au lieu d observer directement la classe à laquelle appartient un sujet, on dispose de renseignements sur chaque sujet, permettant d en déduire la classe à laquelle il appartient avec une certaine probabilité d erreur.
