So,I have already a code for voice output :
<script type="text/javascript">
var msg = new SpeechSynthesisUtterance('Hello World');
window.speechSynthesis.speak(msg);
</script>
But on my smartphone that dont work!(I already tryed with a webside link and as HTML data on phone.)
Thx for every answer!
As you can see here SpeechSynthesisUtterance
isn't supported everywhere and you are apparently using a browser on your phone that doesn't support it.
