Phonetics Calculator Print button

Phonetic algorithms are often used to index words by their pronunciation so they can be compared despite minor differences in spelling. Many genealogy records are indexed this way. The phonetics calculator can generate phonetic codes for a surname using the following algorithms:

  • Soundex
  • New York State Identification and Intelligence System (NYSIIS)
  • Caverphone (2002)
  • Caverphone (2004)
  • Metaphone
  • Double Metaphone
  • Metaphone 3

These algorithms are designed to work with Romanised text only.
