Can't Chrome's speechSynthesis work offline?
问题 I was playing with Chrome's speechSynthesis msg = new SpeechSynthesisUtterance("some text"); msg.lang = "fr-FR" ; window.speechSynthesis.speak(msg); when I discovered this strange issue : it can't speak anymore if your device is offline. I searched the web but did not find any explanation. Can't this work offline ? (If you know the reason why it needs to be online, please tell me it too in the comments.) 回答1: Speech synthesis voices are either local on the device or come from remote speech
