The Caverphone within linguistics and computing, is a phonetic matching algorithm[1][2] invented to identify English names with their sounds, originally built to process a custom dataset compound between 1893 and 1938 in southern Dunedin, New Zealand.
[3] Started from a similar concept as metaphone, it has been developed to accommodate and process general English since then.
[3] The Caverphone was created by David Hood in the Caversham Project at the University of Otago in New Zealand in 2002, revised in 2004.
The algorithm is optimised for accents present in the study area (southern part of the city of Dunedin, New Zealand).
The rules of the algorithm are applied consecutively to any particular name, as a series of replacements.
