Translation:You are talking very noisily today.
I would have said very noisily.
I would too since it's an adverb, I think it might be a mistake.
Is there a reason ‘you speak’ was rejected? (2016-07-01)
I'd say it's because it doesnt make much sense in English. "You speak/talk very noisily today." doesn't spund natural so instead "Speaking/Talking" is used.
