Vegas 365 supports text to speech Dutch, but it is the Dutch variant of The Netherlands, not the Belgian Dutch (= Flemish).
As far as I know Vegas uses Microsoft's Azure, and Azure supports Dutch (Belgium) voice. So, why is this not supported in Vegas?
I do not have anything against Dutchmen, but I would like to hear Dutch speech in my native tongue. Just imagine all US users are forced to select Australian English as text to speech! I know the rest of the world think we speak French in Belgium, but the fact is native speak is roughly divided between 60% Dutch and 40% French.
