[hts-users:01072] Re: about duration model streams

[gues <nkwuzz@xxxxxxxxx>]

But in the duration model mmf structure, only one stream.

How  to get stream number be equal to the number of state?

 

Thank you

No, it's not a bug.

In the previous versions we used a multi-variate Gaussian PDF to represent state duration PDFs.
However, since version 2.0.1 we have changed it to multi-stream structure.
You can find this notation in README file and on the HTS website.

Therefore, # of streams should be equal to the number of states for state duration models.
