Phonetic Search Technology (PST) is a method of speech recognition. An audio signal of speech is broken down into series of phonemes, which can be used to identify words.

What does phonetic search mean?

In the case of a phonetic search, it is a technique to look up a word with the exact spelling along with the words having similar sounds. Let us use a few examples of names having similar sounds but they differ in their spellings.

What is phonetic matching?

In general, phonetic matching lets you search a name list for names that are phonetically equivalent to the desired name. BMPM is similar to a soundex search in that an exact spelling is not required.

What is soundex and Metaphone?

Metaphone expands on Soundex with a wider set of English pronunciation rules and allowing for varying lengths of keys, whereas Soundex uses a fixed-length key. Double Metaphone further refines the matching by returning both a “primary” and “secondary” code for each name, allowing for greater ambiguity.

What is the best phonetic algorithm?

Among the best-known phonetic algorithms are:

Soundex, which was developed to encode surnames for use in censuses. …
Daitch–Mokotoff Soundex, which is a refinement of Soundex designed to better match surnames of Slavic and Germanic origin. …
Cologne phonetics: This is similar to Soundex, but more suitable for German words.

What is phonetic encoding?

Phonetic encoding is a part of the standardization process, and is the process of changing the value of a data field to its phonetic equivalent. It is used to retrieve records with similar field values from the database for matching.

How does beider Morse work?

Beider-Morse Phonetic Matching (BMPM) is a “soundalike” tool that lets you search using a new phonetic matching system. BMPM helps you search for personal names (or just surnames) in a Solr/Lucene index, and is far superior to the existing phonetic codecs, such as regular soundex, metaphone, caverphone, etc.

How does Soundex algorithm work?

The Soundex algorithm generates four-character codes based upon the pronunciation of English words. These codes can be used to compare two words to determine whether they sound alike.

What does Soundex match mean?

Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.
