text-sound-similarity v1.0.2

Text sound similarity

Finds degree of similarity between text's phonetics, based on Metaphone and Dice's Coefficient algorithms.

Install

npm install text-sound-similarity

Usage

import { compareTwoTexts } from 'text-sound-similarity';

compareTwoTexts('lost', 'loose'); // 0.6666666666666666

API

Requiring the module gives an object with three methods:

getTextPhonetic(text)

Returns the string's phonetic got via metaphone algorithm.

Arguments

text (string): The text you want to get as a Metaphone code.

Returns

(string): Metaphone code of the given text

Examples

import { getTextPhonetic } from 'text-sound-similarity';

getTextPhonetic('My name is Laura'); //MNMSLR

compareTwoTexts(text1, text2)

Returns a fraction between 0 and 1, which indicates the degree of similarity between phonemes of the two texts. 0 indicates completely different texts, 1 indicates identical texts

Arguments

1. text1 (string): The first text
2. text2 (string): The second text

Order does not make a difference.

Returns

(number): A fraction from 0 to 1, both inclusive. Higher number indicates more similarity.

Examples

import { compareTwoTexts } from 'text-sound-similarity';

compareTwoTexts('My name is Laura', 'Her name is laura'); //0.7272727272727273

findBestMatch(mainTexts, targetTexts)

Compares each string in mainTexts against each string in targetTexts and returns the most similar pair.

Arguments

1. mainTexts (Array<string>): The string list to match each target string against.
2. targetTexts (Array<string>): Each string in this array will be matched against each string in mainTexts.

Returns

(Object): An object with the following properties:

• text: Best match main string
• target: Best match target string
• rating: Similarity rating of them

Examples

import { findBestMatch } from 'text-sound-similarity';

findBestMatch([
  'Love all, trust a few, do wrong to none.',
  'When a father gives to his son, both laugh; when a son gives to his father, both cry.'
], [
  'It is not in the stars to hold our destiny but in ourselves.',

  Returns:
  {
      text: 'Love all, trust a few, do wrong to none.',
      target: 'It is not in the stars to hold our destiny but in ourselves.',
      rating: 0.34146341463414637
