Hey everyone,
    I'm working on training of HMMs for speech recognition using TIMIT 
database. Can someone tell me if there is a matlab code available for 
it?
What should the topology of the HMM(HMm structure) be? Should it be a 
left to right(Baki's model) and a fully connected model( transitional 
probabilities between all the states?

I appreciate any advice or help. Thank you

Peace on you all,
   
  you can use HTK toolkit for training and testing HMM. You can easily run it from matlab.
   
  about the topology you asked about, you can use the traditional topology which is left to
right with a number of states proportional to the length of the word being trained.
   
  Best Regards

Matlab statistical toolbox has functions like
hmmtrain()   %for training  a given HMM model
hmmestimate()  %for estimating the probability of state transitions.

Sinith.
