Abstract: A method of detecting voice activity includes performing a video analysis on a frame of video signal to determine a position of a user in the frame and to identify one or more beams of a corresponding audio signal associated with a region including the position of the user. The identified one or more beams of audio signal are analyzed to determine whether voice is present in the frame. When a user is not identified during the video analysis of the frame of video signal, audio analysis is not performed on the corresponding frame of audio signal.

Abstract: An advertising system receives from an advertiser at a social networking system an advertisement request, the advertisement request comprising advertisement content and a specification of a target audience for the advertisement content. The advertising system defines a plurality of bid values for the advertisement request. For each of the plurality of bid values, the advertisement system estimates a corresponding value of advertisement reach for the target audience, for example, by estimating a number of users of the target audience for each of whom the given bid value is expected to have resulted in at least one successful impression. The advertiser is provided a visual representation of a bid-reach landscape representing the estimated plurality of advertisement reach values as a function of the plurality of bid values. The advertising system provides, to the advertiser, one or more recommendations for bid values for which corresponding return-on-investment metrics exceed a specified threshold.
