Very interesting. I was thinking if vowels are necessary in the
written English.
Apparently they are, here is the above text with no vowels*:

Interestingly enough, the original text of the portions of the bible
that were written in Hebrew were written with no vowels, no word
breaks, no sentence breaks, and no verse breaks. A continuous flow of
consonants. And apparently, though I don't read 2000 year old Hebrew,
it was readable. Anyone on the list who knows more of this can expand
on it, but from what I've read that's the case.
It would have been more interesting if Shannon had not used
printed language and had dealt with the phonemic transcription of
spoken language instead.
Scrambling the sound? That is impossible to understand.
This experiment is carried on daily in the New York subway system.
And they do not try to scramble.... :)
May be your local international airport is also part of this
experiment, you've got to check!!!
Actually there are a set of transition frequency tables for the
phonemes just as there are for written letters, and some disallowed
transitions that don't happen in the language at all. If you use the
second and third order statistics you can make the same kind of
shrewd guess at what's coming next (the preceeding phonemes having
established a context). The interesting thing about the scramble is
that once you get the first word (which you now have access to
unscrambled) you have even more information with which to move
forward and make subsequent guesses. For each word you need to figure
out, if you have the preceeding text figured out correctly, then you
have a huge amount of contextual information from before that helps
you, and that contextual information along with the frequency tables
for sounds (or letters) give you a very high probability of success.
If you guess a word incorrectly and move on, then your conditional
probability (the next given the preceeding) is in error and you
increase the probability of a mistake.
I always thought those airport announcements were made by someone
with a mouth full of dry cereal.
