Package Exports

character-error-rate
character-error-rate/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (character-error-rate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Character-Error-Rate

npm package for calculating the character-error-rate between two strings to evaluate speech recognition quality. Complexity of levenshtein distance is being improved from O(m*n) to O(min(m,n)).

Prerequisites

This project requires NodeJS (version 8 or later) and NPM. Node and NPM are really easy to install. To make sure you have them available on your machine, try running the following command.

$ npm -v && node -v
6.4.1

Installation

BEFORE YOU INSTALL: please read the prerequisites

Install the npm-package

$ npm i @henning410/character-error-rate

Usage

You can decide if punctuation and capitalization should be considered in the calculation.

 calcCER(reference: string, transcription: string, withPunctuation: boolean, withCapitalization: boolean));

import calcCER from 'character-error-rate';

console.log('CER: ', calcCER('reference text', 'transcription text', true, true));
