Произведите рандомизацию скорости перехода в ResponsiveSlides.js

Question

Я добавляю серию ResponsiveSlides на свой сайт портфолио, и я бы хотел, чтобы они рандомизировали скорость своего перехода, чтобы каждый слайд постепенно переходил к следующему через разные промежутки времени. Я могу изменить скорость на любой фиксированный интервал, но я не знаю, как ее рандомизировать. Вот этот сайт: jcwebandgraphic.com

И вот мой код:

SCRIPT

<script>
    // Slider Functions
    $(function() {
        $('.rslides').responsiveSlides({
            speed: 1000,
            timeout: 3000
        });
    })
</script>
