Designing complex interactions for experiences that target XR headsets can be challenging due to the limited input schemes. Advances in Machine Learning (ML) now allow developers to easily leverage Natural Language Understanding through reusable techniques. The combination of XR+AI is a powerful integration that opens new possibilities for both gaming, entertainment and enterprise scenarios. This intermediate session is an exploration of how speech and language understanding can be used to augment Mixed Reality & VR experiences. We'll explore the use of speech recognition & Natural Language Understanding to build advanced voice commands, translate languages from within XR environments, and also look at the creation of intelligent conversation assistants to be used as interactive entities in Mixed Reality and VR apps & games. In a world where speech is the primary form of input, using Machine Learning to process language input and understand the user's intent is of paramount importance. Nick Landry - Microsoft
