Thank you for suggestions and link about FLOSS speaker recognition
software.
If anybody know some others open source implementations please post on
this list.

There is some basic support for this in Asterisk (www.asterisk.org) for use in conference calls.

$ svn co http://svn.digium.com/svn/asterisk/trunk asterisk-trunk

Open apps/app_meetme.c and search around for "ast_dsp" and that will point you to where it is being done. The hard work is being done in main/dsp.c.
