kaldi final.ie text

Hi all,

How to change the final.ie to text format? and how to obtain the T matrix (i.e., ivector_dim x (feat_dim x num_components) ) from <w> and <M>?

[Daniel Povey]

If there were a program like ivector-extractor-copy it would be possible to do that, but we didn't create that program.  (It would be a very trivial program though).

I don't recall the details, but I believe the algorithm we implemented is not 100% equivalent to the standard approach.  It's something to do with the variances, IIRC-- something we did that was a little more exact than the standard approach.  So I'm not sure that getting that T matrix would do you much good even if there were a way to do that, i.e. you wouldn't be able to slot it into another codebase.  Also we did something slightly different with the offset term in the regression.
