Voirex

About Voirex

Voirex is a robust and useful wrapper of many Speect to Text (Voice Recognition) API. In addition to this, Voirex allows you to add dynamic commands to your web applications.

Actually, Voirex is a Speech to Function library which will updated and developed continuously. The main properties of Voirex;

• Selecting various Voice Recogntion API you want to select

  • HTML5 Web Speech API
  • Google Sound Cloud
  • IBM Watson
  • etc.

• Dynmaic and quick recognition of voice commands

• Add commands easily

• Create a dictation object to convert voice to text easily

• Simulate some commands without microphone

• Pause and resume command recognition

• Text analysis with using Levenshtein Distance Algorithm

• Prefering the language which you want

• Taking object property as function and running according to similarity of VoiceText and keywords which you want

• Ability to work with different Javascript environments(Vanilla.js, Node.js, ES6, ES5 etc.)

Installation

NPM

  npm install voirexx

Or just download a .zip package and with the source code, minified file and commands examples with React.js.

How to use

Voirex is totally written in ES6, but it can be transpiled on every version to Javascript. Manager.js cover the main class of Voirex. And all of them converted to ES5 codes under the dist folder.

    dist
        |
        --voice-assistant.umd.js -
        |
        --voice-assistant.cjs.js -
        |
        --voice-assistant.esm.js -

If you import Voirex into your we application projects, you can use this codes,

import Voirex from 'voirexx';

let recognition = new Voirex(
  {
    type: 'browserDefault',
    lang: 'tr-TR'
  },
  {
    keyword: ['Hi', 'Hello'],
    func: myfunc,
    accuracy: '52%',
    pref: 'max'
  }
);

Explanation of above code:

Voice Type

type: 'browserDefault': the which recognition API you want select

lang: 'tr-TR' : Language you want to select

Command

keyword: ['Hi', 'Hello']: keywords which analyze with voice text

func: myfunc: function which you want to do

accuracy: '52%': over which accuracy of analysis function run

pref: 'max': If there are keywords more than one, as which one voirex run

Basic Usage

With using Voirex Speech to function API, adding command is so easy.

//importing voirex
import Voirex from 'voirexx';

//creating a voirex object to start the recognition
let recognition = new Voirex(
  {
    type: 'browserDefault',
    lang: 'tr-TR'
  },
  {
    keyword: ['Hi', 'Hello'],
    func: myfunc,
    accuracy: '52%',
    pref: 'max'
  }
);


//setting a new recognition 
let new_reco = recognition.setVoiceRecConfig();

//start the recognition
recognition.startRecognition(new_reco);

//stop the recognition 
recognition.stopRecognition(new_reco);

//getting instruction of voice (Voice Text)
new_reco.onresult = (event) => {
    recognition.resultProcessVoiceRecog(recognition.getVoiceText(event));
}

With the above code you can;

• do Dynamic Voice Recognition by selecting one of Voice Recognition APIs which integrated with Voirex,
• analyze the similarity of voice text and your keywords with Levenshtein Distance Algorithm like {hi: '35.252365', hello: '80.5562255'}
• compare your accuracy and levenshtein accuracy, according to the result you can run the func
• get the voice text

As I mentioned above, you can easily install and import Voirex and with very little row code you can embed your web app.

checkingVoiceApi(): Check the Voice Selected API you selected is integrated with Voirex or not

console.log(recognition.checkingVoiceApi())

$> true

checkActualAccuracy(voiceText): Get the Levenshtein distance between keywords and Voice Recognition Text

console.log(recognition.checkActualAccuracy(recognition.getVoiceText(event)))

$> {hi: '81.54654654', hello: '12.252156'}

checkMax(voiceText): Taking maximum distance percentage of keywords Levenshtein Accuracy

console.log(recognition.checkMax(voiceText))

$> 81.256256

checkMin(voiceText): Taking minimum distance percentage of keywords Levenshtein Accuracy

console.log(recognition.checkMin(voiceText))

$> 81.256256

checkingVoiceText(voiceText): Check the voice text is emptyor not

console.log(recognition.checkingVoiceText(voiceText))

$> 'voiceText'

Warning

* All the error related between Javascript and Voirex return -1. Developers can check their code error with this way.

For Example

If the browser does not support Voirex, setVoiceRecConfig() method return then, if you use a uncommon browser, you can check the browser support feature by writing the value of setVoiceConfig() method.
