Soundex codes begin with the first letter in the word and followed by a series of numbers representing successive consonants. Use the Soundex strategy to assign the same code to words that sound similar. Configure the Soundex depth to define the number of alphanumeric characters that the strategy returns.

This strategy focuses on the sound of words instead of spelling, it can group alternate spellings and minor spelling variations. For example, the Soundex codes for

Smyth

and

Smith

are the same.

The Soundex strategy can also group mispronounced words. For example, the Soundex codes for the names

Edmonton

and

Edmonson

are the same.
