SoundEx promises a great deal - that of matching words with similar sounding words, but actually delivers, at best, a large number of inaccurate matches. Is there either a There are times when similar words do not have the same Soundex encoding. The initialization of the Soundex Coding System is started in the Initialization folder in the development tools with the Initialization of Soundex tool. Here’s an example of using SOUNDEX()in a database query. Therefore, if you have two words that are pronounced exactly the same, but they start with a different letter, they’ll have a different Soundex string. Like this.

Here’s an example of where two words sound the same (or very similar), and therefore, they share the same Soundex string: Here’s an example of where two words don’t sound the same, and therefore, they have different Soundex strings: As you can see, the Soundex string is completely different for these two words. This code is the sound value that is calculated using the Soundex algorithm according to their sound in the English language. For example all the following names will all result in a Soundex code of "S530" - smith, Smith, smythe, smitt, shmidt, shmidt, snith, snyth, snythe, smmith, etc. I have a database table that has a column of SQLServer Soundex encoded last name + first name.
