Hello Steve,

We have implemented the standard T-matrix
estimation and the corresponding i-vector extraction
procedures (see [1]), which to my knowledge is not available
for Kaldi. I believe the existing code in kaldi is based on the SGMM
setup (see [2] as pointed out by the code).

We will soon upload our report describing the implementation and
differences.
