Phonetics

Phonetic matching (sounds-like) matching can be done with the SoundEx or Metaphone algorithms

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     cadmium_phonetics:
       github: cadmiumcr/phonetics

2. Run shards install

Usage

require "cadmium_phonetics"

sound_ex = Cadmium.sound_ex
metaphone = Cadmium.metaphone

sound_ex.process("phonetics")
# => "P532"

sound_ex.tokenize_and_phoneticize("Ruby aint got nothing on Crystal")
# => ["R100", "A530", "G300", "C234"]

# Keep word stops
sound_ex.tokenize_and_phoneticize("Ruby aint got nothing on Crystal", true)
# => ["R100", "A530", "G300", "N352", "O000", "C234"]

sound_ex.compare("phonetix", "phonetics")
# => true

metaphone.process("phonetics")
# => "FNTKS"

metaphone.tokenize_and_phoneticize("Ruby aint got nothing on Crystal")
# => ["RB", "ANT", "KT", "KRSTL"]

# Keep word stops
metaphone.tokenize_and_phoneticize("Ruby aint got nothing on Crystal", true)
# => ["RB", "ANT", "KT", "N0NK", "ON", "KRSTL"]

metaphone.compare("phonetix", "phonetics")
# => true

Both classes can also be used with attached String methods. The default class for String methods is Metaphone. The attached methods are phonetics, sounds_like, and tokenize_and_phoneticize.

"Crystal".phonetics
# => "KRSTL"

"Crystal".sounds_like("Krystal")
# => true

"Crystal".phonetics(nil, Cadmium::SoundEx)
# => "C234"

# Using a max length
"Constitution".phonetics(6, Cadmium::SoundEx)
# => "C52333"
