var myText = speechSynthesisUtteranceInstance.text; speechSynthesisUtteranceInstance.text = 'Hello I am speaking';
Value
A DOMString
representing the text to the synthesised. The maximum length of the text that can be spoken in each utterance is 32,767 characters.
Examples
var synth = window.speechSynthesis; var inputForm = document.querySelector('form'); var inputTxt = document.querySelector('input'); var voiceSelect = document.querySelector('select'); var voices = synth.getVoices(); ... inputForm.onsubmit = function(event) { event.preventDefault(); var utterThis = new SpeechSynthesisUtterance(inputTxt.value); var selectedOption = voiceSelect.selectedOptions[0].getAttribute('data-name'); for(i = 0; i < voices.length ; i++) { if(voices[i].name === selectedOption) { utterThis.voice = voices[i]; } } console.log(utterThis.text); synth.speak(utterThis); inputTxt.blur(); }
