-  Returns an integer value that indicates the difference between the SOUNDEX values of two character expressions.  
+This function returns an integer value measuring the difference between the [SOUNDEX()](./soundex-transact-sql.md) values of two different character expressions.

 ## Remarks  
- The integer returned is the number of characters in the SOUNDEX values that are the same. The return value ranges from 0 through 4: 0 indicates weak or no similarity, and 4 indicates strong similarity or the same values.  
+`DIFFERENCE` compares two different `SOUNDEX` values, and returns an integer value. This value measures the degree that the `SOUNDEX` values match, on a scale of 0 to 4. A value of 0 indicates weak or no similarity between the SOUNDEX values; 4 indicates strongly similar, or even identically matching, SOUNDEX values.  
   
- DIFFERENCE and SOUNDEX are collation sensitive.  
+`DIFFERENCE` and `SOUNDEX` have collation sensitivity.  
   
 ## Examples  
- In the first part of the following example, the `SOUNDEX` values of two very similar strings are compared. For a Latin1_General collation `DIFFERENCE` returns a value of `4`. In the second part of the following example, the `SOUNDEX` values for two very different strings are compared, and for a Latin1_General collation `DIFFERENCE` returns a value of `0`.
