Abstract: Social network initiated listings can be implemented by using keyword extraction of a social network post containing a sell code. The extracted keywords can be categorized using a machine based categorization system. The listing user account of the post creator can he identified using active session analysis. A listing is created using the listing user account. A new post that contains a URL to the listing is then programmatically published on the social network.

Abstract: In a system and method for voice activity detection (VAD) including: obtaining audio frames from a multi-microphone array; calculating steered response power (SRP) values of the audio frames; calculating entropy levels based on the SRP values; detecting a sequence of audio frames in which the entropy levels are substantially constant across the sequence of frames and denoting an entropy level of the sequence as a background entropy; identifying an incoming audio frame as containing voice activity if the difference between a level of entropy of the current audio frame and the background entropy is larger than a first threshold, and as not containing voice activity otherwise.
