| Abstrakt |
|---|
| In this paper, we have investigated into JFA used for speaker
recognition. First, we performed systematic comparison of full
JFA with its simplified variants and confirmed superior performance
of the full JFA with both eigenchannels and eigenvoices.
We investigated into sensitivity of JFA on the number
of eigenvoices both for the full one and simplified variants. We
studied the importance of normalization and found that genderdependent
zt-norm was crucial. The results are reported on
NIST 2006 and 2008 SRE evaluation data. |
