Abstract
A system automatically frames locations by detecting a user's presence within a virtual detection space. The system detects sound in the detection space and converts the sound into electrical signals. The electrical signals are converted into a digital signals at common or periodic sampling rates. The system identifies speech segments in the digital signals and attenuates noise like components within or adjacent to them. The system identifies the physical locations of a speech source generating the speech segments and automatically adjusts a camera framing based on the estimated location of the active speech source generating the speech segments.
