基于Matlab编写的语音端点检测程序

我是坏坏

<P>学习学习<BR>谢谢分享</P>

<P>斑竹在北京吗，可否指教一下，我的毕设题目只是做yes和no的识别，能不能帮帮忙阿，有酬金（多少合适开个价），我后天就得教了</P>

我是研究语音端点检测的，happy可以把你的端点检测程序发给我学习学习吗？

老大，我需要端点检测程序啊，着急用啊，看到了
千万与我联系，好吗？
我ＱＱ：２４０３８３６８０

老大，我把这段程序拷到 MATLAB里也不能运行呀，为啥呀，提示我：

??? Undefined command/function 'enframe'.
Error in ==> vad at 23
tmp1  = enframe(x(1:end-1), FrameLen, FrameInc);

谁能帮帮忙，怎么改一下可以运行，我的是matlab7.0

看看版规，注意用词。

那个应该是个子函数，主任没有贴出来想必是在另外的地方可以找到的。

不好意思啊，我刚来论坛的，不太清楚规矩。
我找了好多地方，整个论坛，包括网上其他地方也都找了，但是都是这段程序，我刚接触MATLAB，不知道怎么改，可以指点一下么，需要加点什么才能看到运行结果?

有可能发的时候遗漏了这个函数

这里给出enframe函数:
function f=enframe(x,win,inc)
%ENFRAME split signal up into (overlapping) frames: one per row. F=(X,WIN,INC)
%
%        F = ENFRAME(X,LEN) splits the vector X up into
%        frames. Each frame is of length LEN and occupies
%        one row of the output matrix. The last few frames of X
%        will be ignored if its length is not divisible by LEN.
%        It is an error if X is shorter than LEN.
%
%        F = ENFRAME(X,LEN,INC) has frames beginning at increments of INC
%        The centre of frame I is X((I-1)*INC+(LEN+1)/2) for I=1,2,...
%        The number of frames is fix((length(X)-LEN+INC)/INC)
%
%        F = ENFRAME(X,WINDOW) or ENFRAME(X,WINDOW,INC) multiplies
%        each frame by WINDOW(:)

真是太谢谢了，可以运行了，谢谢！
这个论坛挺好，速度快，人也都不错:victory: :victory: :victory:

我找了好久了,难啊 .
很难遇到你这种好人的了,
毕业设计完成后请你喝酒,能来不.
