I would like to read the text of my pages with SpeechSynthesisUtterance.
I found this script: /
Almost perfect, but the pause button doesn't seem to do much, and I wish I had the ability to set a language and maybe choose a voice.
I found the reference here: , but I'm not very knowledgeable in JavaScript.
For language, as far as I understand, should be used the lang parameter set in the html tag.
For the voice I have absolutely no idea of how to implement it in the code.
It would be important because I have texts in English, Spanish, French and Italian, and the result without voice and language settings sometimes sounds really weird.
Update
These days I fiddled a little, I managed (more or less) to bine two different scripts/examples.
This: /
and this:
The code that came out is this:

Now I have the play, stop and pause buttons (pauses still does not work) and I can select one of the voices from those available in the device.
Seems to work fine with chrome, maybe a little less with Firefox, (but I'm using Linux LMDE, maybe it's my fault). And after a while on Chrome stops talking. I don't know why, but it seems to me that I've seen someone maybe understand why in some of the thousands of web pages I've opened these days, I'll have to reopen them all.
It would be nice if the selected voice was saved in a cookie, so if I open another page the script starts with the last voice I selected (I have no idea how to do it in JavaScript)
Update 2
I made some other small steps forward and simplified.
It almost seems to work, not always the pause button, the big doubt I have now is that with chrome it does not seem to stop when I update or change pages, and it is really bad that when you change page he keeps reading the previous page.

Update 3
I tried to add a cookie with the last selected voice. I added a couple of functions to manage the cookies, and I set the cookie in the onClickPlay() function.
//add voice//
var selectedOption = voiceSelect.selectedOptions[0].getAttribute('data-name');
for(i = 0; i < voices.length ; i++) {
//if(voices[i].name === 'Google UK English Female') {
if(voices[i].name === selectedOption) {
utterance.voice = voices[i];
setCookie('SpeechSynthesisVoice',voices[i].name,30);
break;
}
}
Firefox sets the cookie without problems, chrome no (even if the file is on an online server).
Then I tried to set the voice saved in the cookie as "selected" in populateVoiceList() function:
//get cookie voice
var cookievoice = getCookie('SpeechSynthesisVoice');
//add selcted to option if if cookievoice
if (cookievoice === voices[i].name) {
option.setAttribute('selected', 'selected');
}
It works, I find the "selected" in the code, but it doesn't seem to be considered, it always starts talking with the first voice in the list, or the default one, I'm not sure, and not with the one that has the "selected".
The cookie functions I use:
//cookie functions
function setCookie(name, value, days) {
var expires = '',
date = new Date();
if (days) {
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = '; expires=' + date.toGMTString();
}
document.cookie = name + '=' + value + expires + '; path=/';
}
function getCookie(name) {
var cookies = document.cookie.split(';'),
length = cookies.length,
i,
cookie,
nameEQ = name + '=';
for (i = 0; i < length; i += 1) {
cookie = cookies[i];
while (cookie.charAt(0) === ' ') {
cookie = cookie.substring(1, cookie.length);
}
if (cookie.indexOf(nameEQ) === 0) {
return cookie.substring(nameEQ.length, cookie.length);
}
}
return null;
}
function eraseCookie(name) {
createCookie(name, '', -1);
}
I would like to read the text of my pages with SpeechSynthesisUtterance.
I found this script: https://www.hongkiat./blog/text-to-speech/
Almost perfect, but the pause button doesn't seem to do much, and I wish I had the ability to set a language and maybe choose a voice.

document.cookie = name + '=' + value + expires + '; path=/';

function getCookie(name) {

i,
cookie,
nameEQ = name + '=';
for (i = 0; i < length; i += 1) {
cookie = cookies[i];
while (cookie.charAt(0) === ' ') {

}
if (cookie.indexOf(nameEQ) === 0) {
return cookie.substring(nameEQ.length, cookie.length);
}
}
return null;
}
function eraseCookie(name) {
createCookie(name, '', -1);
}
- This reads like a journal entry. Can I ask what the question is? – Frazer Commented Nov 8, 2019 at 8:18
- Pause button doesn't work... and I want add lang and permit the visitor to chose a voice from all the voices in the device – alebal Commented Nov 8, 2019 at 21:13
- Speech synthesis isn't handles the same by all browsers; that code won't always work on Chrome or Firefox for example. The flag the code uses to determine if there is speech running is superfluous as speech will queue. I suggest using separate pause and resume buttons. – Frazer Commented Nov 9, 2019 at 15:51

Reset to default 4I didn't receive much help, but somehow I managed to set up a small player that reads the text of a web page.
I did a little tutorial with a demo that explains what I did and how it works.
https://www.alebalweb-blog./85-text-to-speech-player-with-buttons-play-pause-stop-and-voice-choice.html
How about this line after the "for" loop?
voiceSelect.selectedIndex = selectedIndex;
If it's still here you're overriding your selection. Try something like
if(cookievoice === voices[i].name) {
option.setAttribute('selected', 'selected');
selectedIndex = i;
}
