How to turn on always the microphone in bot framew

I'm creating a bot which accept text and voice input and also can answer in both mode. The bot works really good but i have to click always the button of microphone to speak with the bot. Do you know it is possible to make microphone always on and to recognize the voice without clicking the button of microphone ?

    var botConnection = new BotChat.DirectLine({
     secret: "zzzzzzzzzz",
    webSocket: true,

BotChat.App({
        speechOptions: speechOptions,
        botConnection: botConnection,
        user: {
            id: 'userid',
            name: 'User',
        },
        bot: { id: 'botid' },
        resize: 'detect',
        locale: 'en-US'

    },

function postHelp() {
    botConnection
        .postActivity({
            from: { id: 'userid', name: 'User' },
            name: 'postHelp',
            type: 'message',
            text: 'help'
        })
        .subscribe(function(id) {
            console.log('"postHelp" sent');
        });
};

function welcome() {
    botConnection
        .postActivity({
            from: { id: 'userid', name: 'User' },
            name: 'welcome',
            type: 'event',
            value: 'help'
        })
        .subscribe(function (id) {
            console.log('"welcome" sent');
        });

You cannot just turn on such a behavior. To have something like this, you have to implement the whole thing yourself, editing the code of the web chat control. The web chat control is using the Direct Line API under the hood through the DirectLineJS library.
