Copying the result of one div to a textarea-div

I'm working on a system, which should have the option to be be controlled via speech using the Webspeech API. My problem or question is: How do I copy the result of the voice recognition (which is stored in the "transcript-div") to the "usercomment textarea-div". Like the user says something and the recognized string should be copied to the usercomment automatically.

The corresponding lines of code:
The voice Recognizer:

    var recognition = new webkitSpeechRecognition();
    var final_transcript = '';
    var interim_transcript = '';
    var language = 'en-GB'; 

    recognition.continuous = true; // keep processing input until stopped
    recognition.interimResults = true; // show interim results
    recognition.lang = language; // specify the language

    recognition.onresult = function (event) {
        // Assemble the transcript from the array of results
        for (var i = event.resultIndex; i < event.results.length; ++i) {
            if (event.results[i].isFinal) {
                final_transcript = event.results[i][0].transcript;
            } else {
                interim_transcript = event.results[i][0].transcript;
            }
        }

        console.log("interim: " + interim_transcript);
        console.log("final: " + final_transcript);

        // update the web page
        if (final_transcript.length > 0) {
            $('#transcript').html(final_transcript);
        }

        if (interim_transcript.length > 0) {
            $('#interim').html(interim_transcript);
        }

For debugging purpose I've created another div, which shows the recognized phrases. This is working! 

<div id="console" style="margin-top: 100px;">  
<h3>Console:</h3>  
    <div id="transcript"></div>  
    <div id="interim"></div>  
</div>

And now the content of the "transcript-Div" should be copied to the usercomment-textarea-Div: 

<div id="UsercommentDiv" style="margin-top: 100px;">  
    <br> User Comment :<br> <textarea id="usercomment" style="width: 300px; height: 150px;" name="description" onLoad="fillUsercomment();"></textarea><br>
</div>

I've tried to do this by the following function: 

function fillUsercomment(){
document.getElementById('usercomment').innerHTML = document.getElementById('transcript').innerHTML
}  
fillUsercomment();

The fillUsercomment function works (when I call the function manually, it pastes the content to the usercomment textarea. But how I have to change the code, to paste the recognized output on the fly in the textarea?

Thanks!

Take innerHTML of the div and apply it as value to the textarea (demo):

var div = document.getElementById("transcript");
var txt = document.getElementById("usercomment");

txt.value = div.innerHTML;

Or jQuery way:

$("#usercomment").val($("#transcript").html());

Edited

If final_transcript is the recognition result string you want to append, here:

// update the web page
if (final_transcript.length > 0) {
    $('#transcript').html(final_transcript);
}

you should append "final_transcript" to textarea's value:

var txt = $("#usercomment");
txt.val(txt.val() + final_transcript);

Here is your updated fiddle (look on 17 and 18 lines of JavaScript).

You can read what is val() function does here

Use jQuery

$("#usercomment").attr("value", $("#transcript").text() );

or

 $("#usercomment").val( $("#transcript").text() );

P.S. Sorry I misunderstood at first, I edited now.
