Language Processing and recognition (MFCC as Feature Extraction & HMM classfication)

hai there,

currently i doing my thesis(follows as the title) i have done the MFCC as the FE. now i doing the training part and testing phase.
for training i using the Baum-Welch algorithm and viterbi for recognition.

1)my question is my log-likelihood from my training set is in positive value. i am not sure whether it acceptable o not? i doing on the nepali language.

2) i have got some viterbi path. not sure how to make use of it? help me in that too

My matlab code:

%%%%%%%%Training of HMM (Baum-Welch algorithm)%%%%%%
[LL, prior1, transmat1, mu1, Sigma1, mixmat1] = ...
mhmm_em(data1, pi, transmat, mu, Sigma, mixmat, 'max_iter', 5);
mixmat1 = max(mixmat1, 1.0e-5);

%%%% Calculate the Log Likelihood %%%%%%
[loglik, errors] = mhmm_logprob(data1, prior1, transmat1, mu1, Sigma1, mixmat1);
loglik


i really hope anyone can help in this.. i would really appreciate it and once done i will share my code for your reference and future students as well..thanks ...this is my email if wana contact me. premen87@gmail.com

*** Bless u all
