In a nutshell, you can see it here on Sefaria: https://tinyurl.com/y2qgtuyx

It's a Mishna in Nedirim 3:1, discussed in Talmud 23a, codified in
Yoreh De'a 211 to which the Ba'er Heitev decides that as long as one
said it loud enough to be heard to one's own ears, it's valid.

None of the commentators along the way mention publicity. The only
issue they have is "Devorim She'B'Leiv" if it's whispered or thought.

Along the way I learnt:

You can say it ("just kidding about the Neder stuff") any time.

Those who hold you don't have to say it right before making the Neder,
don't give it an expiration date - IOW once a lifetime should be
sufficient.

Bottom line: If it works, you can chant the "futuristic" Kol Nidrei to
yourself in an undertone. CLOR.
