The google translate page allow the user to translate between different languages. https://translate.google.com.hk/?sl=en&tl=zh-TW&op=translate&hl=en
I can write a javascript clicking the microphone button to continuously translate the speech.
setInterval(function () {
document.getElementsByClassName('EmVfjc qs41qe lSo1Re BbO7g')[0].click();
}, 1000);
But that does not my demand as it clear the translated data. How can I get the underlying event listener for the microphone button?
