I get what you're asking, but don't get what you're expecting as an answer. SWIM has interacted with everything from english speaking entities, to high pitched gibberish speaking entites for whom language was merely an aural wave upon which intention was transmitted and contained no actual phonemes or identifiable linguistic charactersitics. There is audio of McKenna imitating the machine elves language, it's in the She Who Remembers Archive recordings, I believe. It's very hard to convey in words the qualities of these languages, it really requires hearing them.
