According to the description German audio (speech) is not available. Is this still true?

I do speak English, as you may notice, and I can follow English conversations without problems — if the speakers are native speakers! My hearing is not the best any more, and although I turned my hearing aids up, I missed half of what Poirot said while watching the trailer because of his terrible accent. :(

So, if no German audio is available, I'd rather not buy this game.
