KNphone

KNphone is a phonetic algorithm for indexing Kannada words by their pronunciation, like Metaphone for English. The algorithm generates three Romanized phonetic keys (hashes) of varying phonetic affinities for a given Kannada word. This package implements the algorithm in Go.

The algorithm takes into account the context sensitivity of sounds, syntactic and phonetic gemination, compounding, modifiers, and other known exceptions to produce Romanized phonetic hashes of increasing phonetic affinity that are very faithful to the pronunciation of the original Kannada word.

• key0 = a broad phonetic hash comparable to a Metaphone key that doesn't account for hard sounds and phonetic modifiers
• key1 = is a slightly more inclusive hash that accounts for hard sounds.
• key2 = highly inclusive and narrow hash that accounts for hard sounds and phonetic modifiers.

Examples

Word	Pronunciation	key0	key1	key2
ಅಂಕೆಸಂಖ್ಯೆ	aŋkesaŋkhye	A3KS3KY	A3KS3KY	A3K6S3KY6
ಊಱಿಸಾಱು	ūṛisāṛu	URSR	UR1SR1	UR14SR15
ಈರಿತ	īrita	IR0	IR0	IR40
ಒನಮಾಲೆ	onamāle	ONML	ONML	ONML6

Go implementation

Install the package: go get -u github.com/knadh/knphone

package main

import (
	"fmt"

	"github.com/knadh/knphone"
)

func main() {
	k := knphone.New()
	fmt.Println(k.Encode("ಅಂಕೆಸಂಖ್ಯೆ"))
	fmt.Println(k.Encode("ಊಱಿಸಾಱು"))
}
