JavaScript ion applications cannot recognize voice in Android Mobile

• Android

I want to design an ion application that can listen for voice commands by following the tutorial here, but if I use VaR identification = new webkitspeechrecognition(); After the test, it seems that the application can recognize the voice command on the microphone. / / to the computer command. But when I see this post, I replace the command with

Var identification = new speechrecognition()// To device

But it doesn't seem to work on my Android device. Has anyone encountered the same problem as speechrecognition plugin? Please share your thoughts and comments... Thank you

resolvent:

The trick is to add Cordova media plugin

The working code is as follows:

index.html

<!DOCTYPE html>
<html>
    <head>        
        <Meta name="format-detection" content="telephone=no">
        <Meta name="msapplication-tap-highlight" content="no">
        <Meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
        <link rel="stylesheet" type="text/css" href="css/index.css">
        <title>Speech Recognition</title>
    </head>
    <body>      
        <br>
        <br>
        <br>
        <br>
        <br>
        <br>
        <br>
        <br>
        <form>
        Click to speak <input type="button" value="speak" name="Download" id="speak" />  <br>
        <input type="text" id="q" name="q" size=60>
        </form>

        <script type="text/javascript" src="js/jquery.js"></script> 
        <script type="text/javascript" src="cordova.js"></script>
        <script type="text/javascript" src="js/app.js"></script>
    </body>
</html>

app.js

$(document).ready(function() {
    document.addEventListener("deviceready", onDeviceReady, false);
});

var recognition;
function onDeviceReady() {  

    $('#speak').click( function() {
        recognition = new SpeechRecognition();          
        recognition.onresult = function(event) {
            if (event.results.length > 0) {
                console.log(event.results[0][0].transcript);                
                q.value = event.results[0][0].transcript;
            }
        };      
        recognition.start();
    });
}
