exp2
录制汉语拼音 a1(阴平)的发音。分别提交你所能录制的基音频率最高和最低的两个
录音文件。文件名为: 学号_a_h.wav(高音文件)和学号_a_l.wav(低音文件)。(用MathLab
编程)
1)分别对这两个文件进行观察分析。找出最高和最低基音频率位置,分别显示此时它们的
局部波形和短时频谱(按照最大值为100 归一化显示)。
要求:在时域波形上标出基音周期,并算出数值(精确到一个采样点)。在频域图上标出
基音频率。注意:标出分析波形的起始位置(精确到采样点位置),说明谱分析时所采用
的窗函数。
2)用倒谱分析法,估计语音产生模型的声道传输函数H(w)的模|H(w)|。在1)的频谱图上叠
加显示H(w), (按照最大值为100 归一化显示)。
3)用线性预测分析方法,估计语音产生模型的声道传输函数H( )的模| H( ) |。并在 1)
的频谱图上叠加显示H( ) 。(no no non )

Title: "Modeling Lung Cancer Diagnosis Using Bayesian Network Inference"
This demo illustrates a simple Bayesian Network example for exact probabilistic inference using Pearl s message-passing algorithm.
Introduction:
Bayesian networks (or belief networks) are probabilistic graphical models representing a set of variables and their dependencies.
The graphical nature of Bayesian networks and the ability of describing uncertainty of complex relationships in a compact manner provide a method
for modelling almost any type of data.
