Question

我想知道是否有人可以帮助我解决一个棘手的问题，即将一个Praat Pitch轮廓的时间和频率提取到txt文件。

我从

开始

File type = "ooTextFile"
Object class = "Pitch 1"

xmin = 0 
xmax = 1.592 
nx = 159 
dx = 0.01 
x1 = 0.006002267573695814 
ceiling = 1900 
maxnCandidates = 2 
frame []: 
    frame [1]:
        intensity = 0 
        nCandidates = 1 
        candidate []: 
            candidate [1]:
                frequency = 0 
                strength = 0.9 
    frame [2]:
        intensity = 0 
        nCandidates = 1 
        candidate []: 
            candidate [1]:
                frequency = 0 
                strength = 0.9 
    frame [3]:
        intensity = 0 
        nCandidates = 1 
        candidate []: 
            candidate [1]:
                frequency = 763.0480724135344 
                strength = 0.9 
    frame [4]:
        intensity = 0 
        nCandidates = 1 
        candidate []: 
            candidate [1]:
                frequency = 763.3612753914916 
                strength = 0.9 
....

我想去：

0,0
t1,0
t2,763.0480724135344
t3,763.3612753914916 
....
tn, ...

如果脚本可以读取＆＃34; dx =＆＃34;中的信息也会很棒。并计算x坐标的时间。

提前感谢您的帮助。

我一直在研究一些程序来快速将不同的对象类型转换为它们的表示，而Pitch对象相对简单。试试这个：

# Execute this with your Pitch object selected
@pitchToTable()

procedure pitchToTable ()
  .obj = selected("Pitch")
  .name$ = extractWord$(selected$(), " ")
  .t1 = Get time from frame number: 1
  .m1  = To Matrix
  .m2  = Transpose
  .tor = To TableOfReal
  .id  = To Table: "Time"
  Set column label (index): 2, "F0"
  Formula: "Time", "'.t1' + (Object_'.obj'.dx * (row - 1))"
  Formula: "F0", "if self then self else undefined fi"
  Rename: .name$ + "_pitch"
  removeObject: .m1, .m2, .tor
endproc

转换利用了大多数Praat对象可以转换为Matrix对象的事实，该对象基本上已经是一个Table。在这种情况下，唯一需要进行的操作是转置（具有垂直表），并重命名列。

将Praat音高文件中的文本提取到另一个文本文件
