I'm making a bot to listen to my voice.  

So i did :

```
this.recognition = new webkitSpeechRecognition();

```

I can do this to start listen :

```
this.recognition.start();

```

And this to stop listen :

```
this.recognition.stop();

```

But do you know a function that will return me true if `this.recognition` is started and false if it's stopped ? Like `"isStarted()"` ?

Thanks.
