Julia White from Microsoft Azure Marketing demonstrated the use of Hololens 2 to project a motion captured holograph of herself speaking in Japanese using her own speech patterns. The demonstration was created using Azure mixed reality to record the hologram, Azure text to speech and translate to create the spoken content and Azure neural text to speech technology to imprint her speech patterns in Japanese. Check out the video demonstration, which also looks like a scene from the Taelon ship in Earth Final Conflict :-p
