Using Google Chrome ttsengine for speech input

I am developing a chrome extension and using tts and ttsengine for speech i/o. But my extension have my chrome to crash without a useful error code (Chrome quits unexpectedly with Process: Google Chrome [888])

When I call the javascript method chrome.experimental.speechInput.start(function(){}) chrome crashes.

I tried another extension provided by google which is Speech Recognizer and it works well, also the speech input in google.com works well. Experimental flag has been set.

Is there any additional permission to give or any other procedure to make speech-to-text work?

My manifest.json:

{
"name": "my_extension",

"version": "0.1",

"manifest_version": 2,

"description": "my description",

"icons": {
    "16": "icon16.png",
    "128": "icon128.png"
},

"app": {
    "launch": {
        "local_path": "/twitter/index.html"
    }
},

"offline_enabled": true,

"permissions": [
    "experimental",
    "unlimitedStorage",
    "https://api.twitter.com/*",
    "ttsEngine",
    "tts"
],

"tts_engine": {
    "voices": [{
        "lang": "de",
        "event_types": ["end"]
    }]
}
}

My .js file:

function startSpeechInput() {
    chrome.experimental.speechInput.onError.addListener(recognitionFailed);
    chrome.experimental.speechInput.onResult.addListener(recognitionSucceeded);
    chrome.experimental.speechInput.onSoundEnd.addListener(recognitionEnded);

    chrome.experimental.speechInput.isRecording(function (recording) {
        if (!recording) {
            chrome.experimental.speechInput.start({ 'language': 'en-US' }, function(){
                            //TODO
                    }

                    console.log("Voice recognition started!");
            });
        }
        else {
            console.log('Pressed Record while it is already recording. Do nothing...');
        }
    });
}
