Xuedong David Huang is also known as XD because his email is xdh. Huang’s current responsibility at Microsoft is to incubate new businesses that would drive Microsoft's future growth. Before he took the incubation GM job in October 2004, Huang was the general manager of Microsoft's Speech Platforms Group overseeing the product development, research, marketing, and business development of Microsoft’s speech technologies. Huang founded Microsoft’s speech technology and business units that shipped core speech technologies across Microsoft’s product lines (Server, Windows, Office, and Mobility).

In 1978 Huang was admitted to Hunan University in his beautiful home town Changsha, China when he was 15. Driven by working with world-class teams, Huang went to Beijing's Tsinghua University for his graduate study on Artificial Intelligence. He moved to Scotland and finished his PhD work on speech technology in less than 2 years at the University of Edinburgh. His PhD thesis work won IEEE’s prestigious Paper Award. Before recruited by MS in 1993, Huang led the Carnegie Mellon University team achieving not only the best system in 1992's DARPA speech benchmarking but also the most dramatic error reduction in the history of DARPA's speech evaluations. Huang and his team received 1992 Alan Newell research excellence medal. Huang was also recognized multiple times as the top 10 leaders of the speech industry by SpeechTek.

He cares deeply about the community and co-established "Spoken Language Processing Grant" with Alex Acero and Hsiao-Wuen Hon at IEEE to provide financial aids for students to travel to IEEE-sponsored conferences. He also serves in the IT advisory board for the Governor of Hunan, China, as well as the Honorary Dean/Professor of Institute of Software Engineering at Hunan University, where he grew up and had his wonderful childhood there. He is married to Yingzhi Zhou when he studied at Tsinghua University in Beijing and is the proud father of Angela, Christina, and Derek. He enjoys watercolor painting in his spare time, partly inspired by his Hunan artistic friends.
