> a general purpose scheme to find word with similar phonemes.

> digits. These three digits are determined by dropping the letters a, e, i, o,

> or more consecutive letters have the same code, they are coded as one letter.
> (2) If there are an insufficient numbers of letters to make the three digits,
> the remaining digits are set to zero.
