Set of different phonetic encoders' implementations.

$ go get -v github.com/f1monkey/phonetic
The fastest algorithm in this library. Soundex is used to encode words into a phonetic code for matching similar sounding words with different spellings. It was developed for indexing English language names. Wiki page.
Code example:
package main
import (
"fmt"
"github.com/f1monkey/phonetic/soundex"
)
func main() {
e := soundex.NewEncoder()
result := e.Encode("orange")
fmt.Println(result)
// prints: O652
}The Metaphone encoder converts words into a phonetic code that represents their pronunciation for comparing words based on their phonetic properties, rather than their spelling. The Metaphone encoder was designed for English. Wiki page
Code example
package main
import (
"fmt"
"github.com/f1monkey/phonetic/metaphone"
)
func main() {
e := metaphone.NewEncoder()
result := e.Encode("orange")
fmt.Println(result)
// prints: ORNJ
}Cologne phonetics (Kölner Phonetik) is a phonetic algorithm used for indexing German words by their sound, allowing for name and word matching in German language databases. Wiki page
Code example:
package main
import (
"fmt"
"github.com/f1monkey/phonetic/cologne"
)
func main() {
e := cologne.NewEncoder()
result := e.Encode("Großtraktor")
fmt.Println(result)
// prints: 47827427
}Caverphone2 is a phonetic algorithm used for indexing and matching names, particularly in English and New Zealand languages. Wiki page
package main
import (
"fmt"
"github.com/f1monkey/phonetic/caverphone2"
)
func main() {
e := caverphone2.NewEncoder()
result := e.Encode("orange")
fmt.Println(result)
// prints: ARNK111111
}It's a Go port of the original PHP library BMPM is a phonetic algorithm used for indexing and matching names in multiple languages. Contains a huge amount of different rules to transform a word to it's phonetic representation. Current implementation is relatively slow.
To reduce outcoming binary size, the three rulesets were split into different packages:
github.com/f1monkey/phonetic/beidermorse- generic rules (for general usage)github.com/f1monkey/phonetic/beidermorse/beidermorseash- ashkenazi rulesgithub.com/f1monkey/phonetic/beidermorse/beidermorsesep- sephardic rules
Each package contains exact and approx (default) rulesets. To use exact ruleset, you should pass a special option to encoder (see in example).
Code examples:
genericruleset withapproxaccuracyimport ( "fmt" "github.com/f1monkey/phonetic/beidermorse" ) func main() { encoder, _ := beidermorse.NewEncoder() result := encoder.Encode("orange") fmt.Println(result) // prints: [orangi oragi orongi orogi orYngi Yrangi Yrongi YrYngi oranxi oronxi orani oroni oranii oronii oranzi oronzi urangi urongi] }
genericruleset withexactaccuracyimport ( "fmt" "github.com/f1monkey/phonetic/beidermorse" ) func main() { encoder, _ := beidermorse.NewEncoder(beidermorse.WithAccuracy(beidermorse.Exact)) result := encoder.Encode("orange") fmt.Println(result) // prints: [orange oranxe oranhe oranje oranZe orandZe] }
genericruleset withexactaccuracy andenglishlanguage with buffer reusing (to reduce GC pressure)import ( "fmt" "github.com/f1monkey/phonetic/beidermorse" ) func main() { encoder, err = beidermorse.NewEncoder( beidermorse.WithAccuracy(beidermorse.Exact), beidermorse.WithLang(beidermorse.English), beidermorse.WithBufferReuse(true), ) result := encoder.Encode("orange") fmt.Println(result) // prints: [orenk orenge orendS orendZe oronk oronge orondS orondZe orank orange orandS orandZe arenk arenge arendS arendZe aronk aronge arondS arondZe arank arange arandS arandZe] }
ashkenaziruleset withapproxaccuracyimport ( "fmt" "github.com/f1monkey/phonetic/beidermorseash" ) func main() { encoder, _ := beidermorseash.NewEncoder() result := encoder.Encode("orange") fmt.Println(result) // prints: [orangi orongi orYngi Yrangi Yrongi YrYngi oranzi oronzi orani oroni oranxi oronxi urangi urongi] }
sephardicruleset withapproxaccuracyimport ( "fmt" "github.com/f1monkey/phonetic/beidermorsesep" ) func main() { encoder, _ := beidermorsesep.NewEncoder() result := encoder.Encode("orange") fmt.Println(result) // prints: [uranzi uranz uranS uranzi uranz uranhi uranh] }
