[Danaan]

Slavic but more familiar phonetically (to me).

I heard bratrja two, three times.

[Applesandoranges]

i can hear some little similiarity with persian in terms of sounding

[Eurafricanid]

Sounds like a mix of A Slavic language and Italian, so I'm gonna say some old Slavic language?

[Brás Garcia de Mascarenhas]

Old Slavonic.

[Beowulf]

sounds like Old greek for me

[dviz]

Clearly a Slavic language (with easily recognizable words), but spoken with the accent of guy who maybe speaks Latin in church, and who perhaps is not a native speaker of the language.

[Alenka]

Interesting observations thus far. Anyone else want to chime in?

[Dušan]

Is this kajkavian or čakavian?

[Seya]

Some weird slavic dialect...no idea.
