One vocalized word; each version has different audio effects applied to the same word.  The phonetics of the word are somewhat muffled through the filters so that it can be used for various purposes.

These sounds were intended for a “rogue-like” which allowed audio to be conditionally played when any of its various “Zot” messages are seen in the message-box — although, the implementation was buggy and so I doubt these were ever usable with it.
I don't play that game any more, and so I don't know if anyone is using these.

Please note that the Preview is same as ‘Zot_distant.ogg’.
