I tried the translation from German into English with PowerPoint Live Captions with the same sentences I used in my previous post here. The result is shown in the following screenshot. I repeated the sentences twice and spoke a normal speed, not too fast.
The translations are understandable, I think, even if not very accurate. I noticed, e.g. that the first try for the second sentence gave me a funny translation and for the third sentence, the first part of the German sentence was not fully translated. And there are capitalization errors too, I think.
