How can I export my aspell dictionary?

At the moment, I'm working on a big LaTeX document about mathematics and once in a while I do some spell-checking on it. As you can guess, there are a lot of words which are not in a standard dictionary. But I've added them with aspell with a to the standard dictionary. aspell -d de -t -c my-document.tex Is there a way to export my words (and only those)? Restoring seems to be quite simple: another question .
