I mean, there's the old Windows-only SAPI from the Windows XP days that they haven't been developing for several years now, and the current Azure Cognitive Services, which is just a REST API with a pretty standard auth scheme. There's an official .NET package for wrapping that REST API, but it's certainly not necessary to use it if you know how to handle REST APIs. Is that what you're talking about?

Yes, the Azure API, there are 2 different things under the hood, the short and login APIs, that are different names, different auth headers, different voices supported, voices with same name that have different styles supported. Bad errors messages that popup and get fixed in a few days but only on one of the APIs. The issue is that I am trying to combine the short and long APIs in one product and I am hitting this big inconsistencies, I see lcearly there are 2 teams and do things different , if you use only one section you have a completly different experience.

Edit. I do the REST calls directly, not via an SDK and use the documentation from MS for the REST API so no SDK documentation or SDK code that hides the issues.
