A method includes processing a number of media assets stored in one or more media asset repositories to determine a number of signatures for media in time intervals of the media assets of the number of media assets, processing the number signatures to identify duplicate instances of the signatures in the number of signatures, processing the identified duplicate instances to identify relationships between the identified duplicate instances, and storing the number of signatures and the relationships between the identified duplicate instances of the signatures in a signature data store.

Media asset management

A method for preparing supplementary media content for coordinated transmission with multimedia content includes accepting the multimedia content including an audio portion, accepting the supplementary media content associated with the multimedia content, and validating the supplementary media content according to the audio portion of the multimedia content.

Supplementary media validation system

In an aspect, in general, method for aligning an audio recording and a transcript includes receiving a transcript including a plurality of terms, each term of the plurality of terms associated with a time location within a different version of the audio recording, forming a plurality of search terms from the terms of the transcript, determining possible time locations of the search terms in the audio recording, determining a correspondence between time locations within the different version of the audio recording associated with the search terms and the possible time locations of the search terms in the audio recording, and aligning the audio recording and the transcript including updating the time location associated with terms of the transcript based on the determined correspondence.

Transcript re-sync

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.
