20090319269 | Method of Trainable Speaker Diarization - A novel and useful method of using labeled training data and machine learning tools to train a speaker diarization system. Intra-speaker variability profiles are created from training data consisting of an audio stream labeled where speaker changes occur (i.e. which participant is speaking at any given time). These intra-speaker variability profiles are then applied to an unlabeled audio stream to segment the audio stream into speaker homogeneous segments and to cluster segments according to speaker identity. | 12-24-2009 |
20100042412 | SKIPPING RADIO/TELEVISION PROGRAM SEGMENTS - Techniques for notifying at least one entity of an occurrence of an event in an audio signal are provided. At least one preference is obtained from the at least one entity. An occurrence of an event in the audio signal is determined. The event is related to at least one of at least one speaker and at least one topic. The at least one entity is notified of the occurrence of the event in the audio signal, in accordance with the at least one preference. | 02-18-2010 |
20110119060 | METHOD AND SYSTEM FOR SPEAKER DIARIZATION - A method and system for speaker diarization are provided. Pre-trained acoustic models of individual speaker and/or groups of speakers are obtained. Speech data with multiple speakers is received and divided into frames. For a frame, an acoustic feature vector is determined extended to include log-likelihood ratios of the pre-trained models in relation to a background population model. The extended acoustic feature vector is used in segmentation and clustering algorithms. | 05-19-2011 |
20110251843 | COMPENSATION OF INTRA-SPEAKER VARIABILITY IN SPEAKER DIARIZATION - A method, system, and computer program product compensation of intra-speaker variability in speaker diarization are provided. The method includes: dividing a speech session into segments of duration less than an average duration between speaker change; parameterizing each segment by a time dependent probability density function supervector, for example, using a Gaussian Mixture Model; computing a difference between successive segment supervectors; and computing a scatter measure such as a covariance matrix of the difference as an estimate of intra-speaker variability. The method further includes compensating the speech session for intra-speaker variability using the estimate of intra-speaker variability. | 10-13-2011 |
20120191459 | SKIPPING RADIO/TELEVISION PROGRAM SEGMENTS - Techniques for notifying at least one entity of an occurrence of an event in an audio signal are provided. At least one preference is obtained from the at least one entity. An occurrence of an event in the audio signal is determined. The event is related to at least one of at least one speaker and at least one topic. The at least one entity is notified of the occurrence of the event in the audio signal, in accordance with the at least one preference. | 07-26-2012 |
20140029757 | PROVIDING A CONFIDENCE MEASURE FOR SPEAKER DIARIZATION - Method, system and computer product are provided for a computer implemented method for providing a confidence measure for speaker diarization. The method includes: receiving an audio session as unsegmented audio data; computing a spectral ratio of principal component analysis (PCA) of sections of the received audio session by a ratio between the largest eigenvalue and the second largest eigenvalue; using the PCA spectral ratio as a confidence measure for speaker diarization processing. | 01-30-2014 |

20100089181 | Sample Collection System and Method for Use Thereof - A sample collection system capable of collecting, storing and dispensing a liquid sample is disclosed. The collection system includes a collector composed of a material which has the unique ability to express constituents of interest at levels which are much more concentrated than their levels in the fluid samples from which they are expressed, where the expressed highly concentrated sample can then be used with modern rapid screening/testing protocols, such as solid phase assays, to test for the constituents of interest. Thus, it is now possible to obtain analytes of interest, such as the HIV protein antibodies, from saliva samples at concentrations that are representative of that found in serum or plasma. The collector is sized and shaped to fit within a recovery container, which, in turn, is sized and shaped to fit within a collection tube. The recovery container includes an aperture which does not permit passage of fluid under ambient conditions, but facilitates transfer thereof when subjected to pressure. An optional channel within the collection tube facilitates dispensing of the sample for further processing. | 04-15-2010 |
