An apparatus includes voice activity detection (VAD) circuitry configured to analyze one or more audio broadcast streams and to identify first segments of the one or more broadcast streams in which the audio data includes speech data. The apparatus further includes derivation circuitry configured to receive the first segments and, for each first segment, to derive one or more words from the speech data of the first segment. The apparatus further includes keyword detection circuitry configured to, for each first segment, receive the one or more words and to generate keyword information indicative of whether at least one word of the one or more words is among a set of stored keywords. The apparatus further includes decision circuitry configured to receive the first segments, the one or more words of each of the first segments, and the keyword information for each of the first segments and, for each first segment, to select, based at least in part on the keyword information, among a plurality of options regarding communication of information indicative of the first segment to a recipient.
