From: supriya on 17 Jun 2010 08:10 I am unable to find out the flaw in my code (Ref.End point detection algo flowchart., pg-7,Rabiner &_ Sambur-Algo for endpoint detection of isolated utterances.pdf-Available at http://users.ecel.ufl.edu/~dulberg/endpointdetection.pdf). I am a new user..please help? code:- while (E(m)<E_tl) m=m-1; if(E(m)<E_tl) continue; end i=m; if(E(i)<E_tl) m=i-1; continue; end while(E(i)<E_th) i=i-1; if(E(i)<E_tl) break; else continue; end end if(E(i)<E_tl) m=i-1; continue; end N2=i; if(i==m) N2=N2+1; end end -------- Thanks.

Your code appears to be syntactically correct, so it sounds like you've got some testing ahead of you. Working from the flowchart in that paper, create SMALL signals that cover each of the paths through that flowchart and run them BY HAND through the procedure in the flowchart, recording the results at each step. [This is going to be the first hard part of your task.] Then set a breakpoint on the first line of your code and run your code on each of the signals you generated. Watch the contents of the variables (either using the Workspace Browser or by simply typing their names in the Command Window) and look for the first time your results differ from the results you generated by hand. Now that you have a test case that demonstrates the incorrect behavior you can determine WHY the results differ and how to make them the same. [This is the second hard part.] For more information on debugging functions in MATLAB, read this section of the documentation: http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_env/f2-4931.html -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com

There is an alltogether similar loop for beginning point detection except that '+' occurs instead of minus in its code(ex. m=i+1) The problem comes when I enter this part after completing the end point search- my cursor gets lost and the breakpoint also vanishes. And the required variables do not show up in workspace.:( --- Regards, Supriya
