Hey! i m working on continuous speech recognition. i read everything on Hidden Markov Model(HMM), i m not getting how to implement it in Matlab. Can any 1 help me out on how to build model in matlab? i m also not getting what shud be hmm states and hmm observation for my model.. Thanx in advance

Are you done with your HMM based Speech Recognizer? of so, can you share the file with me, i mean the source code for reference. I have no idea where to start and how to develop it from scratch.Also may i know how much time it may involve?

hmm based speech recognition system are really difficult to built.i worked hard 4 months but could not get it.then i changed it to word recognition system based on psd and filter fingerprints.i dont want to demoralize.
here are the links that may help you: http://www.mathworks.in/company/newsletters/digest/2010/jan/word-recognition-system-matlab.html
for any other help just google ,you may get some help from there.here you will get help only if you have some basic idea already .

i want to do word spotting in continuous speech, b4 i tried dtw algorithm but with constraint that input speech shud have reasonable pauses in between each word.. that's y i switched 2 hmm.. i read all about hmm but confused what shud be hmm states.. i got idea that v have 2 take hmm states as vocal tract shapes and each state comprising of phonemes as observations.. but how to identify dese for a particular word.. do help me for identifying hmm states and its observations.
