Just how compressed?

[bellinghman]

I wouldn't have thought a natural language could be expressed in only two vowels and four consonants (or four vowels and four consonants depending on the reports), but apparently Silbo Gomero is.

(A Reuters report on how the brain actually recognises it.)

I'd imagine it's a very lossy compression that requires a lot of context to disambiguate. The most import context being that it's not a general purpose language, but one used for communication between shepherds, hence can be expected to have a smaller core vocabulary than standard Spanish. Not that Spanish is a terribly phonemically rich language to start off with.
