Audio for Kinect: pushing it to the limit
Ivan Tascev (Microsoft)

PRESENTATION SLIDES:S4-Tashev.pdf

ABSTRACT:

This talk will discuss aspects of the acoustical design and audio processing pipeline of Kinect, the most selling electronic device in the human history as recorded in the Guinness Book of Records. The device is the first industrial product with surround sound echo cancellation, one of the first to offer hands free speech recognition from distance up to four meters, and is the first open microphone speech recognition device. The presenter, Dr. Ivan Tashev from Microsoft Research, is one of the architects behind Kinect and created most of the algorithms in the audio pipeline.


SPEAKER BIO:

Ivan Tashev toke his Diploma Engineer in Electronics and PhD in Computer Science from the Technical University of Sofia, Bulgaria, in 1984 and 1990 respectively. He was Assistant Professor in the same university when joined Microsoft in 1998. Currently he is a Principal Architect in Speech Technology Group in Microsoft Research. Dr. Tashev contributed with algorithms and designs to microphone array support in Windows, RoundTable device, the audio pipeline in MicrosoftAuto platform, and the audio pipeline in Kinect. He is inventor or co-inventor of 40 US patent submissions, from which 18 are granted. Ivan Tashev is a senior member of IEEE and member of its Audio and Acoustic Signal Processing Technical Committee. He is also member of the Audio Engineering Society and its Pacific Northwest Committee, and the Acoustical Society of America. Dr. Tashev is reviewer for most of the scientific journals in his research area, member of the organizing or technical committees of ICASSP, IWAENC, WASPAA, HSCMA and other scientific conferences in his area. He authored or coauthored four books and more than 70 scientific papers. His latest book =93Sound Capture and Processing=94 was published in 2009 by John Wiley & Sons Ltd.
