Here's the English translation of the provided Japanese blog article:
This code uses the await keyword with the speech method of SpeechSynthesisUtterance.
It performs the text-to-speech processing in a synchronous manner in a web browser.
However, please note that due to browser security reasons, you cannot make it automatically speak as soon as the browser is opened. The user must click a button or perform some action on the page at least once for the speech synthesis to work.
function asyncSpeak(text) {
const ssu = new SpeechSynthesisUtterance();
ssu.text = text;
ssu.lang = 'en-US';
speechSynthesis.speak(ssu);
return new Promise((resolve, reject) => {
ssu.onend = () => {
resolve();
};
});
}
async function onStarted() {
await asyncSpeak('one two three four five six seven eight nine ten');
console.log('end');
}
