TREND DISCOVERY IN AUDIO SIGNALS
First Claim
1. A method comprising:
- processing, by a keyphrase generation engine, data representative of text associated with one or more content sources to generate a specification of a set of keyphrases of interest;
processing, by a word spotting engine, a first set of audio signals collected during a first time period to generate first data characterizing putative occurrences of one or more keyphrases of the set of keyphrases of interest in the first set of audio signals;
evaluating, by an analysis engine, the first data to generate keyphrase-specific comparison values for the first set of audio signals;
deriving, by the analysis engine, first trending data between the first set of audio signals and a second set of audio signals based in part on an analysis of the keyphrase-specific comparison values for the first set of audio signals relative to stored keyphrase-specific baseline values; and
generating, by a user interface engine, a visual representation of at least some of the first trending data and causing the visual representation of the first trending data to be presented on a display terminal.

Abstract
Techniques for processing data representative of text associated with one or more content sources to generate a specification of a set of keyphrases of interest; processing a first set of audio signals collected during a first time period to generate first data characterizing putative occurrences of one or more keyphrases of the set in the first set of audio signals; evaluating the first data to generate keyphrase-specific comparison values for the first set of audio signals; deriving first trending data between the first set of audio signals and a second set of audio signals based in part on an analysis of the keyphrase-specific comparison values for the first set of audio signals relative to stored keyphrase-specific baseline values; and generating a visual representation of at least some of the first trending data and causing the visual representation of the first trending data to be presented on a display terminal.

processing, by a keyphrase generation engine, data representative of text associated with one or more content sources to generate a specification of a set of keyphrases of interest; processing, by a word spotting engine, a first set of audio signals collected during a first time period to generate first data characterizing putative occurrences of one or more keyphrases of the set of keyphrases of interest in the first set of audio signals; evaluating, by an analysis engine, the first data to identify coocurrences of spoken instances of keyphrases of the set of keyphrases of interest within the first set of audio signals; and generating, by a user interface engine, a visual representation of at least some of the identified cooccurences of the spoken instances of keyphrases and causing the visual representation to be presented on a display terminal. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
