This discussion pops up every few years.  We recently had it again at
cryptography: 

http://lists.randombit.net/pipermail/cryptography/2015-February/007072.html

the usual outcome of these discussions is that the word lists are fine
for English speaking people but problematic for the rest of the world.
This problem is very old and the reason why more than 50 years ago the
ICAO came up with a spelling alphabet to be used on noisy channels and
between people of different mother tongue.

agreed, that is longer than a word list but easier to pronounce and
understand by most people.  And the alphabet is easy to learn so that
the new gpg option is not always needed.


Salam-Shalom,
