Jquery 随机化ResponsiveSlides.js中的转换速度

我在我的公文包网站上添加了一系列的ResponsiveSlides，我想让它们随机化它们的转换速度，这样每一张幻灯片都会以不同的间隔淡入下一张幻灯片。我可以将速度更改为任何固定的间隔，但我不知道如何随机化。以下是网站：jcwebandgraphic.com

这是我的代码：

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