JavaScript Html5 & JavaScript Text to Speech conversion [duplicate] html5 javascript text to speech,html5 javascript text,html5 javascript

The problem with Peter's answer is it doesn't work when you have a queue of speech synthesis set up. The script will put the new chunk at the end of the queue, and thus out of order. Example: https://jsfiddle.net/1gzkja90/

<script type='text/javascript' src='http://code.jquery.com/jquery-2.1.0.js'></script>
<script type='text/javascript'>    
    u = new SpeechSynthesisUtterance();
    $(document).ready(function () {
        $('.t').each(function () {
            u = new SpeechSynthesisUtterance($(this).text());

            speechUtteranceChunker(u, {
                chunkLength: 120
            }, function () {
                console.log('end');
            });
        });
    });

In my case, the answer was to "chunk" the string before adding them to the queue. See here: http://jsfiddle.net/vqvyjzq4/

Many props to Peter for the idea as well as the regex (which I still have yet to conquer.) I'm sure the javascript can be cleaned up, this is more of a proof of concept.

    $(document).ready(function () {
        var element = this;
        var arr = [];
        var txt = replaceBlank($(element).text());
        while (txt.length > 0) {
            arr.push(txt.match(pattRegex)[0]);
            txt = txt.substring(arr[arr.length - 1].length);
        }
        $.each(arr, function () {

Answer:1

A simple and effective solution is to resume periodically.

function resumeInfinity() {
    window.speechSynthesis.resume();
    timeoutResumeInfinity = setTimeout(resumeInfinity, 1000);
}

You can associate this with the onend and onstart events, so you will only be invoking the resume if necessary. Something like:

var utterance = new SpeechSynthesisUtterance();

utterance.onstart = function(event) {
    resumeInfinity();
};

utterance.onend = function(event) {
    clearTimeout(timeoutResumeInfinity);
};

I discovered this by chance!

Hope this help!

Answer:2

I ended up chunking up the text and having some intelligence around handling of various punctucations like periods, commas, etc. For example, you don't want to break the text up on a comma if it's part of a number (i.e., $10,000).

I have tested it and it seems to work on arbitrarily large sets of input and it also appears to work not just on the desktop but on android phones and iphones.

Answer:3

I have solved the probleme while having a timer function which call the pause() and resume() function and callset the timer again. On the onend event I clear the timer.

    var myTimeout;
    function myTimer() {
        window.speechSynthesis.pause();
        window.speechSynthesis.resume();
        myTimeout = setTimeout(myTimer, 10000);
    }
    ...
        window.speechSynthesis.cancel();
        myTimeout = setTimeout(myTimer, 10000);
        var toSpeak = "some text";
        var utt = new SpeechSynthesisUtterance(toSpeak);
        ...
        utt.onend =  function() { clearTimeout(myTimeout); }
        window.speechSynthesis.speak(utt);
    ...

This seem to work well.

Answer:4

Here is what i ended up with, it simply splits my sentences on the period "."

var voices = window.speechSynthesis.getVoices();

var sayit = function ()
{
    var msg = new SpeechSynthesisUtterance();

    msg.voice = voices[10]; // Note: some voices don't support altering params
    msg.voiceURI = 'native';
    msg.volume = 1; // 0 to 1
    msg.rate = 1; // 0.1 to 10
    msg.pitch = 2; //0 to 2
    msg.lang = 'en-GB';
    msg.onstart = function (event) {

        console.log("started");
    };
    msg.onend = function(event) {
        console.log('Finished in ' + event.elapsedTime + ' seconds.');
    };
    msg.onerror = function(event)
    {

        console.log('Errored ' + event);
    }
    msg.onpause = function (event)
    {
        console.log('paused ' + event);

    }
    msg.onboundary = function (event)
    {
        console.log('onboundary ' + event);
    }

    return msg;
}


var speekResponse = function (text)
{
    speechSynthesis.cancel(); // if it errors, this clears out the error.

    var sentences = text.split(".");
    for (var i=0;i< sentences.length;i++)
    {
        var toSay = sayit();
        toSay.text = sentences[i];
        speechSynthesis.speak(toSay);
    }
}
Answer:5

2017 and this bug is still around. I happen to understand this problem quite well, being the developer of the award-winning Chrome extension Read Aloud. OK, just kidding about the award winning part.

  1. Your speech will get stuck if it's longer than 15 seconds.
  2. I discover that Chrome uses a 15 second idle timer to decide when to deactivate an extension's event/background page. I believe this is the culprit.

The workaround I've used is a fairly complicated chunking algorithm that respects punctuation. For Latin languages, I set max chunk size at 36 words. The code is open-source, if you're inclined: https://github.com/ken107/read-aloud/blob/master/js/speech.js (line 144)

The 36-word limit works well most of the time, staying within 15 seconds. But there'll be cases where it still gets stuck. To recover from that, I use a 16 second timer.

Answer:6

As Michael proposed, Peter's solutions is really great except when your text is on different lines. Michael created demo to better illustrate the problem with it. - https://jsfiddle.net/1gzkja90/ and proposed another solution.

To add one maybe simpler way to solve this is to remove line breaks from textarea in Peter's solution and it works just great.

//javascript
var noLineBreaks = document.getElementById('mytextarea').replace(/\n/g,'');

//jquery
var noLineBreaks = $('#mytextarea').val().replace(/\n/g,'');
Answer:7

Other suggestion do weird thing with dot or say DOT and do not respect speech intonnation on sentence end.

var CHARACTER_LIMIT = 200;
var lang = "en";

var text = "MLA format follows the author-page method of in-text citation.

The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence.

Answer:8

Yes, the google synthesis api will stop at some point during speaking a long text.

We can see onend event, onpause and onerror event of SpeechSynthesisUtterance won't be fired normally when the sudden stop happens, so does the speechSynthesis onerror event.

After several trials, found speechSynthesis.paused is working, and speechSynthesis.resume() can help resume the speaking.

Hence we just need to have a timer to check the pause status during the speaking, and calling speechSynthesis.resume() to continue. The interval should be small enough to prevent glitch when continuing the speak.

let timer = null;
let reading = false;

let readText = function(text) {

    if (!reading) {
        speechSynthesis.cancel();
        if (timer) {
            clearInterval(timer);
        }
        let msg = new SpeechSynthesisUtterance();
        let voices = window.speechSynthesis.getVoices();
        msg.voice = voices[82];
        msg.voiceURI = 'native';
        msg.volume = 1; // 0 to 1
        msg.rate = 1.0; // 0.1 to 10
        msg.pitch = 1; //0 to 2
        msg.text = text;
        msg.lang = 'zh-TW';

        msg.onerror = function(e) {
            speechSynthesis.cancel();
            reading = false;
            clearInterval(timer);
        };

        msg.onpause = function(e) {
            console.log('onpause in ' + e.elapsedTime + ' seconds.');
        }            

        msg.onend = function(e) {
            console.log('onend in ' + e.elapsedTime + ' seconds.');
            reading = false;
            clearInterval(timer);
        };

        speechSynthesis.onerror = function(e) {
            console.log('speechSynthesis onerror in ' + e.elapsedTime + ' seconds.');
            speechSynthesis.cancel();
            reading = false;
            clearInterval(timer);
        };

        speechSynthesis.speak(msg);

        timer = setInterval(function(){
            if (speechSynthesis.paused) {
                console.log("#continue")
                speechSynthesis.resume();
            }

        }, 100);
