The soundex system to encode names was developed in 1918 by Robert C. Russell.
It gives a short string to show roughly how the first part of a name (or other word) sounds when spoken. To find the soundex of a name, first write the letters of the name. Then go through the following steps:
1. delete the first letter of the name (but keep a record of it);
2. delete any A, E, I, O, U, Y, H, or W;
3. replace letters by numbers, as follows:
use 1 for B, F, P or V;
use 2 for C, G, J, K, Q, S, X or Z;
use 3 for D or T;
use 4 for L;
use 5 for M or N;
use 6 for R;
4. if two or more adjacent numbers are the same, omit all but one;
5. if there are more than three numbers, keep only the first three; if fewer than three, add 0s to the end to make the code up to three numbers;
6. put the first letter of the original name on the front of the code.
Sample Problem 1.1 Find the soundex representations of the names SPRINGER and HAMMAN.
