New Hololens Dev/ Designer!

Hey guys, I'm Erika! I just got a Hololens 2 for some dev work and have previously worked with the Quest 2 and 3. I'm new to using the MRTK and would love some guidance as to where I can begin with the cognitive services such as Speech to text translation and object recognition! I'm also a content creator and would like to see how cross compatible the MRTK is with my different XR headsets and integrating AI. Thank you in advance and looking forward to the future ahead! Woohoo for innovation!
