彼得回答的问题是当您设置语音合成队列时它不起作用。该脚本会将新块放在队列的末尾，因此无序。示例：https : //jsfiddle.net/1gzkja90/
<script type='text/javascript' src='http://code.jquery.com/jquery-2.1.0.js'></script>
<script type='text/javascript'>
u = new SpeechSynthesisUtterance();
$(document).ready(function () {
$('.t').each(function () {
u = new SpeechSynthesisUtterance($(this).text());
speechUtteranceChunker(u, {
chunkLength: 120
}, function () {
console.log('end');
});
});
});

就我而言，答案是在将字符串添加到队列之前“分块”字符串。见这里：http : //jsfiddle.net/vqvyjzq4/
许多支持 Peter 的想法以及正则表达式（我还没有征服它。）我相信 javascript 可以清理，这更像是一个概念证明。
