Can screen readers be told to ignore certain text?

I was thinking of using a CSS technique to create a drop shadow effect on some titles. This would result in the html having what amounts to duplicate text:

[code]
<h1 class=shadow>Some Title</h1>
<h1 class=top>Some Title</1>
[/code]

So what I’m wondering is, is there some technique via CSS or HTML to tell accessibilty tools like text-to-speach readers or such to ignore certain text (in this case, ignore the [font=courier][color=green]<h1 class=shadow>Some Title</h1>[/color][/font] line)?
