摘要： A method for determining a similarity between a first audio source and a second audio source includes: for the first audio source, determining a first frequency of occurrence for each of a plurality of phoneme sequences and determining a first weighted frequency for each of the plurality of phoneme sequences based on the first frequency of occurrence for the phoneme sequence; for the second audio source, determining a second frequency of occurrence for each of a plurality of phoneme sequences and determining a second weighted frequency for each of the plurality of phoneme sequences based on the second frequency of occurrence for the phoneme sequence; comparing the first weighted frequency for each phoneme sequence with the second weighted frequency for the corresponding phoneme sequence; and generating a similarity score representative of a similarity between the first audio source and the second audio source based on the results of the comparing.

摘要： In one aspect, a method for processing media includes accepting a query. One or more language patterns are identified that are similar to the query. A putative instance of the query is located in the media. The putative instance is associated with a corresponding location in the media. The media in a vicinity of the putative instance is compared to the identified language patterns and data characterizing the putative instance of the query is provided according to the comparing of the media to the language patterns, for example, as a score for the putative instance that is determined according to the comparing of the media to the language patterns.

摘要： 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.

摘要： Some general aspects relate to systems and methods for media processing. One aspect, for example, relates to a method for aligning multimedia recording with a transcript. A group of search terms are formed from the transcript, with each search term being associated with a location within the transcript. Putative locations of the search terms are determined in a time interval of the multimedia recording. For each search term, zero or more putative locations are determined and, for at least some of the search terms, multiple putative locations are determined in the time interval of the multimedia recording. According to a first sequencing constraint, a first representation of a group of sequences each of a subset of the putative locations of the search terms is formed. A second representation of a group of sequences each of a subset of the search terms is formed. Using the first and the second representations, the time interval of the multimedia recording is partially aligned with the transcript.

摘要： A method for speaker adaptation includes receiving a plurality of media files, each associated with a call center agent of a plurality of call center agents and receiving a plurality of terms. Speech processing is performed on at least some of the media files to identify putative instances of at least some of the plurality of terms. Each putative instance is associated with a hit quality that characterizes a quality of recognition of the corresponding term. One or more call center agents for performing speaker adaptation are determined, including identifying call center agents that are associated with at least one media file that includes one or more putative instances with a hit quality below a predetermined threshold. Speaker adaptation is performed for each identified call center agent based on the media files associated with the identified call center agent and the identified instances of the plurality of terms.
