分段动态时间包装 [英] Segmental Dynamic time wraping

问题描述

大家好.

我正在进行语音处理项目关键字发现"，并且需要Matlab代码来实现分段动态时间规整"算法

实际上我有2个字符串，第一个是代表发声的长字符串，第二个是代表模板关键字的小字符串.

我必须将小字符串与长字符串的每个部分进行比较.该怎么做?

我正在研究的方法使用分段动态时间包装，但我无法理解.

有谁能够帮助我?

我很快就需要，
最好的问候.Shayan

Hello everybody.

I''m working on a speech processing project "Keyword Spotting" and I need a Matlab code for "Segmental Dynamic time Warping" algorithm

Actually I have 2 strings, the first one is a long string that represents the utterance and the second one is a small string that represents a template keyword.

I have to compare the small string with each portion of the long string.How can I do that?

The approach that I''m working on it uses Segmental Dynamic time Wrapping But I can not understand it.

Can anybody help me?

I need it quickly,
Best regards.Shayan

推荐答案

如果我对您的理解正确，则您正在尝试在Matlab中的另一个字符串中查找字符串...如果是这样，请使用 strfind() [较低 [ ^ ]或全部上 [

If I understand you correctly, you''re trying to find one string within another in Matlab... if so, use strfind()[^]. Be aware that the function is case sensitive, if you want to make it case insensitive, just make both strings either all lower[^] or all upper[^] before making the function call.
