Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. Similar sounding words receive an identical Soundex code. The SOUNDEX() function accepts a string and converts it to a four-character code based on how the string sounds when it is spoken. It finds out the phonetic value of the string you give it.Phonetic means that it looks the way that it sounds. If two words sound similar, but not exactly the same, their Soundex string might look similar but not exactly the same. The goal is for names with the same pronunciation to be encoded to the same representation so that they can be matched despite minor differences in spelling. The letters A, E, I, O, U, H, W, and Y are ignored if they are not the first letters of the string. This example uses the SOUNDEX() function to return the SOUNDEX code of both string 'sea' and 'see': The SOUNDEX codes are the same because see and  sea have the same sound. Example. 400% schnellere Version. These are the top rated real world Python examples of soundex.soundex extracted from open source projects. 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. Soundex is the most widely known of all phonetic algorithms and is often used (incorrectly) as a synonym for "phonetic algorithm". Surnames that sound similar, like Miller and Müller, are also coded to the same Soundex. The SOUNDEX() function will add zeros at the end of the result code if necessary to make a four-character code. Calculating the difference between Soundex codes. Modify the code as follows to make it work with Oracle for performance queries from VB; ' Check to see if the current code is the same as the last one If (CurrCode <> PrevCode) Then ' Check to see if the current code is 0 (a vowel); do not proceed In this case, we’re looking for any records that sound like “Ay See Dee Ci”: So AC/DC apparently has the same Soundex code as Ay See Dee Ci (at least when using MySQL) Just to be sure, here’s the Soundex codes for both of those strings: An alternative query could have been constructed using SOUNDS LIKE instead of the SOUNDEX() function. For example, there are different spellings for my surname: Schwitzgebel, Schwitzgoebel, Switsgable. In this case, we’re looking for any records that sound like “Ay See Dee Ci”: Result: So AC/DC apparently has the same Soundex code as Ay See Dee Ci(at least when using MySQL) Just to be sure, here’s the Soundex codes for both of those strings: Result: Hat das zu codierende Wort so viele Buchstaben, dass man mehr Ziffern erzeugen könnte, bricht man nach der dritten Ziffer ab. 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. Examples: Oracle SOUNDEX function .

It returns a value that represents the phonetic value of a string.What does that mean?Well, you know that the letter “a” in “apple” sounds different to the letter “a” in “army”? To check the similarity between SOUNDEX codes of two strings, you use the DIFFERENCE() function. You can rate examples to help us improve the quality of examples. These codes can be used to compare two words to determine whether they sound alike. The most common reason for this is that they start with a different letter, one of which is a silent letter. You can then take that number and compare it to Soundex codes for other names that encode to that same number. The following example uses the SOUNDEX() function to get the codes for the string 'coffee' and 'black' which have different sounds: In this tutorial, you have learned how to use the SQL Server SOUNDEX() function to get the SOUNDEX code of a string.
