Just a little pointer to 'Bubble Babble':
'In computing, Bubble Babble is a binary data encoding designed by Antti
Huima. This encoding uses alternation of consonants and vowels to encode
binary data to pseudowords that can be pronounced more easily than
arbitrary lists of hexadecimal digits.'[0]

If someone wants to play with it, there is also a Perl Module[1].
