Проблема с ответом Питера в том, что он не работает, когда у вас настроена очередь синтеза речи. Сценарий поместит новый фрагмент в конец очереди и, следовательно, не в порядке. Пример: https://jsfiddle.net/1gzkja90/.

u = new SpeechSynthesisUtterance();
$(document).ready(function () {
$('.t').each(function () {
u = new SpeechSynthesisUtterance($(this).text());
speechUtteranceChunker(u, {
chunkLength: 120
}, function () {
console.log('end');
});
});
});

В моем случае ответ заключался в том, чтобы «разбить» строку перед добавлением их в очередь. См. Здесь: http://jsfiddle.net/vqvyjzq4/
Много реквизитов Питеру за идею, а также за регулярное выражение (которое мне еще предстоит освоить). Я уверен, что javascript можно очистить, это скорее доказательство концепции.
