SYSTEM AND METHOD FOR SPOKEN TOPIC OR CRITERION RECOGNITION IN DIGITAL MEDIA AND CONTEXTUAL ADVERTISING

摘要

Systems and methods for automated analysis and targeting of digital media based upon spoken topic or criterion recognition of the digital media are provided. Pre-specified criteria are used as the starting point for a top-down topic or criterion recognition approach. Individual words used in the audio track of the digital media are recognized only in context of each candidate topic or criterion hypothesis, thus yielding greater accuracy than two-step approaches that first transcribe speech and then recognize topic based upon the transcription.
