Subject: [PATCH] Fix using speak/speak_active without a `text` beforehand

Otherwise, it would end up indexing a vector out-of-bounds, which is UB
and causes a segfault, too. This is used in some constructs like

    say(-1)
    <internal command>

where the text contents don't matter, only that a text box shows up.
