[web2py] calling a fuction from javascript (jquery)

[pk]

hi i need help,

how can i call a function from jquery with parameters for example:

$('nao_speak').click(function(event){
        event.preventDefault();
        var naotext = $('naospeak').val();

        $.ajax({ url: "{{=URL(r=request,c='speak',f='NaoSpeak')}}",
naotext});  
        console.log('Nao is speaking');
});

i want to call the function NaoSpeak and the variable naotext should
be given to this function.
how can i solve this problem?

thanks.
