javascript - 我的 annyang 程序出错

Question

我正在尝试实现这个 annyang 程序:

<script src="//cdnjs.cloudflare.com/ajax/libs/annyang/1.1.0/annyang.min.js"></script>
<script>
    if (annyang) {
        // Let's define our first command. First the text we expect, and then the function it   should call
        var commands = {
            'show tps report': function() {
                $('#tpsreport').animate({bottom: '-100px'});
            }
        };

        // Add our commands to annyang
        annyang.addCommands(commands);

        // Start listening. You can call this here, or attach this call to an event, button, etc.
        annyang.start();
    }

    else{
        alert("Error alert");
    }
 </script>

问题是我收到“错误警报”消息，但我没有找出原因？

Answer 1

SpeechRecognition 在 Firefox(桌面版本 29)中不起作用，请参阅:

(function () {
    var b = this;
    console.log(b.SpeechRecognition); // undefined
    console.log(b.webkitSpeechRecognition); // undefined
    console.log(b.mozSpeechRecognition); // undefined
    console.log(b.msSpeechRecognition); // undefined
    console.log(b.oSpeechRecognition); // undefined
}).call(this);

SpeechRecognition 需要像“Google Chrome”这样的浏览器
