You can easily do this using setInterval and few lines of code.

Working demo

var keywords = ["awesome", "cool", "fantastic", "incredible"];
var count = 1;
setInterval(function(){    
    $("span.keyword").fadeOut(400, function(){        
        $(this).html(keywords[count]);        
        count++;        
        if(count == keywords.length)            
            count = 0;        
        $(this).fadeIn(400);    
    });
}, 2000);
