gender of speaker?

[barbarakelley.livejournal.com]

The greeting (forgive spelling) Spraznikum. Most people seem to say it with the M on the end, others distinctly say "spraznika" with no M. I've read that some words in Russian would be said differently by a female speaker than they would be by a man; is this one of them? Or is this some local variation?

Thanks,
Barbara
