Note: This software was developed for version 1933 of Kaldi, that is the version required by the Kaldi baseline for Track 2 of the 2nd CHiME challenge. It may work without change for slightly more recent versions of Kaldi, but it must be adapted in order to work with the latest version.

Use

The result is a new executable: gmmbin/gmm-latgen-faster-unc which is identical to gmmbin/gmm-latgen-faster except that it takes feature vectors consisting of the concatenation of the mean and the variance of the features as input.
