文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem. Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors. The models are used to design first, second etc. order predictors. The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The best prediction scheme obtains an average spectral distortion that is 0.46 dB less than for the reference method. )

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)
