Sorry, currently Speech SDK does not support .netcore on Mac yet. (Please find supported languages and platforms here. We will add it at a later time, but I do not have any date yet at this point.

@zhouwangzw
I thought all .netcore2.x projects where multiplatform and I figured I could use this example to then move the code to mobile platforms like android and iOS using xamarin and c#. I'm very motivated to see this happen so if you need help with anything, be it brainstorming, rubber ducking or grunt work with lines of code, you can count on me to try and make this SDK truly multiplatform.

BTW, thanks for answering so fast

[zhouwangzw]

Thank you for your willingness for help! Multiplatform and multi-language support is definitely one of important features we want to provide.

The Speech SDK currently uses native C++ implementation in core, and then adds different language bindings on top of that. That is the reason why SDK currently only supports .netcore on Windows and Linux. We will add support for more platforms in future.

Thank you again!

As Zhou said - this will come, but no ETA yet. I'm closing this here now, we have this on our to-do list, we will publish some more detailed plan for platform support in the next month(s).

@wolfma61 @zhouwangzw Thanks a lot for your replies!

Just wanted to tell you that @jimbobbennett made a binding of the android speech sdk. Hope it serves you (:

Here are the links to the articles he wrote about it:

thank you for the about!
we ill take a very close look asap and see if we can accelerate integration
