I'm working on speech recognition project and I'm having trouble in using kmeans and hmmtrain MATLAB function.

What I have is, features extracted per frame(89 frames in total) and clustered using kmeans function. To work on hmmtrain function, I need sequence and estimate_TR and estimate_EM. I decided to use hmmestimate to obtain these.

I have states obtained as cluster numbers from kmeans. But sequence is where I'm having trouble.

I suppose sequence would be the same data used for kmeans clustering. But my data is negative and less than zero and cannot be used as sequence since sequence should be positive integers. Is there any way out? If my understanding isn't correct, could anybody tell me what would be my sequence? Will it be frame number??

Yes, it is frame number.
