代码说明:

应用背景在这个实验中,你使用的顺序序列的能量概念的分类语音为浊音和清音帧。这是通过将你的选择的语音信号分为短帧和通过计算每个帧的平均功率来完成的。如果其平均功率超过了由用户选择的阈值电平,则该特定帧中的语音将被声明为。否则就是宣布清音。更具体地说,如果一个框架有氮的样品,然后这些样品的平方值被添加和总和(这是能量的帧)被划分为n的结果被取为平均功率的帧,它是由用户设置的阈值水平相比。我们在这里执行的处理是相当琐碎的,因为它涉及的离散时间信号或序列的分割和平均。然而,操作是有用的,可以让我们将言为浊音或清音。关键技术浊音和清音的定义如下。语音是由音素,这是由声带和声道的制作(包括口腔和嘴唇)。浊音信号时产生的声带振动一个音素的发音中。相比之下,清音信号,不需要声带的使用。例如,音素 之间唯一的区别;/ / / z /  ; ;或 ;/ F /  ;和 ;/ V /  ;是声带振动。浊音信号往往是更像元音 ;/ /,/ /,/我/,/ u /,/。 ; ;清音信号,另一方面,更倾向于突然像塞音 ;/ P /,/ T /,/ K /。这个平均功率是框架的响度指示。 ;因此我们预计 高平均功率;声音信号比 ; ;清音 ;信号。用户在1和0之间选择一个阈值,它更接近于0,用户应该能够通过实验来选择合适的值。

    We present in this paper a new method for blind source separation which is adapted to the case where the sources have different morphologies. We show that the morphology diversity concept leads to a new and very efficient method, even in the presence of noise.

    说明:  最小均方濾波器是一類可通過最小化誤差訊號之均方值而修正濾波器係數,以類比所需理想濾波器的自適應濾波器,其中作為修正依據的誤差訊號為理想參考訊號與實際輸出訊號之差。該種濾波器所用之最小均方法只以當前之訊號誤差值為準進行修正,是一種隨機梯度下降法。最小均方法係由斯坦福大學的Bernard Widrow教授及他的首位博士班學生Marcian Hoff於1960年提出。最小均方濾波器屬於常見的自適應濾波器種類之一。(The minimum mean square filter is an adaptive filter that can correct the filter coefficients by minimizing the mean square value of the error signal to analogize the desired ideal filter. The error signal used as the correction reference is the ideal reference signal and the actual output. The difference between the signals. The minimum averaging method used in this kind of filter is only corrected based on the current signal error value, which is a stochastic gradient descent method. The minimum mean method was proposed in 1960 by Professor Bernard Widrow of Stanford University and his first PhD student, Marcian Hoff. The least mean square filter is one of the common types of adaptive filters.)
