Normally when we have to match or compare strings,
we give so much focus on spelling for exact match.
Today's world of Artifical Intelligence and Machine Learning,
comparing with spelling only can miss out so much information
that we cannot imagine.
Very often, people misspells and due to the reason we may not get
required output.
Phonetic/Soundex algorithms can become very useful
in comparing and matching
words by their pronunciation instead of spelling check.
In the beginning phonetic/soundex algorithms
were implemented in order to analyse
US census data.
Phonetic algorithms and few other algorithms
have been playing important role in spelling correction,
database record mapping and search recommendations(
we can see when we misspell in the google search box and
corrects and recommends).
I have written simple Phonetic/Soundex Algorithm in Java Programming
language for your reference.
