That's what S/Key (and its successor systems) do. Quoting RFC 2289:
The one-time password generated by the above procedure is 64 bits in
length. Entering a 64 bit number is a difficult and error prone
process. [...] The one-time password therefore
MAY be converted to, and all servers MUST be capable of accepting it
as, a sequence of six short (1 to 4 letter) easily typed words that
only use characters from ISO-646 IVCS. Each word is chosen from a
dictionary of 2048 words; at 11 bits per word, all one-time passwords
may be encoded.
The two extra bits in this encoding are used to store a checksum. [...]
The OTPs spit out look like TERN FANG DINT TOG WRY BAWL, which is certainly
better than the hex.
See the RFC (one copy at
<A HREF="ftp://coast.cs.purdue.edu/pub/tools/unix/skey/docs/rfc2289.txt">ftp://coast.cs.purdue.edu/pub/tools/unix/skey/docs/rfc2289.txt</A> ) for the
actual dictionary.

If you can get enough information crammed in there. I'm reminded of the
LambdaCore $wiz_utils:random_password function, which make random
consonant-vowel-consonant-vowel-etc strings of specified length. There are
6 vowels and 17 consonants (c, f, and k removed to help avoid rude-sounding
random strings). So, if you know a random password is from this generator
and is of length 6, there are only (6 * 17) ^ 3 possibilities....
