Disable Custom Taxonomy Archive Title

Hi,
I'm using the following snippet to disable category archive titles:

add_action( 'wp', 'tu_remove_category_title' );
function tu_remove_category_title() {
    if ( is_category() ) {
        remove_action( 'generate_archive_title', 'generate_archive_title' );
    }
}

But how would I do the same for Custom Taxonomy Archive titles?

Thanks,
Andy
