Google Assistant fails to resolve some spoken German channel names

Switching the channel via voice command basically works via schalte auf Kanal <Kanal> command. The TV however fails to resolve some of the German/Austrian channel names, especially those with written out numbers inside. The full channellist can be downloaded here.
