Problems solved by technology

[0006] However, with this conventional indexing technique, there are cases where the similarity between segments cannot be accurately judged due to adverse effects of noise, and thus accurate indexing cannot be performed.
Therefore, accurate indexing of various types of acoustic signals is not possible

no. 1 example

[0025] figure 1 is a block diagram showing the functional structure of the indexing device 10 for indexing acoustic signals using the indexing system according to the first embodiment of the present invention.

[0026] The indexing device 10 includes an acoustic signal acquisition unit 102 , a division unit 104 , an acoustic model generation unit 106 , a reliability determination unit 108 , a similarity vector generation unit 110 , a grouping unit 112 and an indexing unit 114 .

[0027] The acoustic signal acquisition unit 102 acquires an externally input acoustic signal through a microphone or the like. The division unit 104 receives the acoustic signal from the acoustic signal acquisition unit 102 . Then, the division unit 104 divides the acoustic signal into segments, for example using information about power or zero-crossing values.

[0028] figure 2 The operation of the dividing unit 104 is shown. The dividing unit 104 uses the dividing points 210a to 210d as boundar...

Abstract

An indexing apparatus includes an acquiring unit that acquires an acoustic signal; a dividing unit that divides the acoustic signal into a plurality of segments; an acoustic model producing unit that produces an acoustic model for each of the segments; a reliability determining unit that determines reliability of the acoustic model; a similarity vector producing unit that produces a similarity vector having elements that are the similarities between the acoustic model for a predetermined segment and the acoustic signal of each of the other segments, based on the reliability; a clustering unit that clusters similarity vectors produced by the similarity vector producing unit; and an indexing unit that indexes the acoustic signal based on the similarity vectors clustered.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application Serial No. 2004-270448 filed on September 16, 2004; the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an indexing apparatus, an indexing method, and an indexing program for providing an index for an audio signal. Background technique [0004] By conventional indexing methods known for indexing acoustic signals, each acoustic signal is divided into segments, and the similarities between the segments are used to classify the segments. An indexing method utilizing the similarity between segments is disclosed by Yvonne Moh, Patrick Nguyen and Jean-Claude Junqua et al. . [0005] By indexing acoustic signals, large amounts of stored data can be efficiently processed. For example, speaker information indicating which speaker each voice signal among TV broadcast progra...
