Each Soundex code consists of one letter and three numbers, such as G616, no matter how long the name is. If "H" or "W" separate two consonants that have the same soundex code, the consonant to the right of the vowel is not coded. The pairs in this example have different Soundex strings solely because their first letter is different. To convert names to Soundex codes, … Every computer scientist has heard of SoundEx.
