Detailed Description

Factor analysis that models speaker variability, remaining speaker variability and channel variability.

The GMM model (supervector = concatenation of all GMM means) can be factorized to two supervector $M=s+c$. $s$ describes speaker variability and $c$ describes channel variability. $c=u x$ where $u$ is low rank rectangular matrix (eigenchannels) and $x$ are channel factors. And $s = m + v y + d z$. $m$ is speaker- and channel-independent supervector, $v$ is rectangular low rank matrix (eigenspeakers) $y$ are speaker factors, $d$ is diagonal matrix and $z$ is a vector with remaining speaker variability.
