Speech Signal Similarity
First Claim
1. A method for determining a similarity between a first audio source and a second audio source, the method comprising:
- for the first audio source, performing the steps of;
determining, using an analysis module of a computer, a first frequency of occurrence for each of a plurality of phoneme sequences in the first audio source;
determining, using the analysis module, 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, performing the steps of;
determining, using the analysis module, a second frequency of occurrence for each of a plurality of phoneme sequences in the second audio source;
determining, using the analysis module, a second weighted frequency for each of the plurality of phoneme sequences based on the second frequency of occurrence for the phoneme sequence;
comparing, using a comparison module of a computer, the first weighted frequency for each phoneme sequence with the second weighted frequency for the corresponding phoneme sequence; and
generating, using the comparison module, a similarity score representative of a similarity between the first audio source and the second audio source based on the results of the comparing.

Abstract
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.

14. A method for determining a similarity between a first audio source and a second audio source, the method comprising:
-
generating, using a computer, a phonetic transcript of the first audio source, the phonetic transcript including a list of phonemes occurring in the first audio source; searching the second audio source for each phoneme included in the phonetic transcript using the computer; generating, using the computer, an overall search result for the second audio source, the overall search result including results from the searching; and generating, using the computer, a score representative of a similarity between the first audio source and the second audio source, the score based on the overall search result. - View Dependent Claims (15)

16. A method comprising:
-
comparing an audio track of a first multimedia source with an audio track of a second multimedia source, the second multimedia source being associated with text content corresponding to closed captioning; determining a similarity score representative of a similarity between the audio track of the first multimedia source and the audio track of the second multimedia source based on the results of the comparing; and associating at least some of the text content corresponding to the closed captioning with the first multimedia source if the determined similarity score exceeds a predefined threshold. - View Dependent Claims (17)

18. A method comprising:
-
processing signals received over a plurality of channels, each channel being associated with a distinct one of a set of geographically dispersed antennas, to determine a similarity score representative of a similarity between pairs of the received signals; and for each pair of the received signals having a determined similarity score that exceeds a predefined threshold, determining whether the received signals of the pair are time aligned, and if so, removing from further processing one of the received signals of the pair. - View Dependent Claims (19)
