Hi, I am wondering if anyone can help at all. What I need to do is to find the minimum edit distance path between 2 sounds(wavfiles), sound A and sound B. they will need to be divided into 40 ms frames and then I need to find matching frames ie. the ones with the lowest distance. I then need to return the time of the matched frame. In other words, I know the time of a vowel in sound A but need to find the time of this vowel in sound B by using the minimum edit distance!! Can anyone help??????? Thanks, Sara

No I am dividing the words into phones e.g. cheer will be divided up into ch-ee-r , so three phones. I have the timings for the fricatives e.g. ch and r but I need the timing of -ee- from the user's entry so the minimum edit path is what I need to get this. so basically I will have each phone in the stored speech sample assigned to a value and whichever user's sample matches the vowel in the stored sample when following the min distance path, I need to retrieve the timing from this vowel.
