The talk discusses 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.
