Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > Recognition > Creating Patterns For Matching > Clustering ClusteringClustering patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.09/21/06 - 20060212294 - Apparatus and method for analysis of language model changes An apparatus, a method, and a machine-readable medium are provided for characterizing differences between two language models. A group of utterances from each of a group of time domains are examined. One of a significant word change or a significant word class change within the plurality of utterances is determined. ... 08/10/06 - 20060178884 - Interactive clustering method for identifying problems in speech applications A method of aiding a speech recognition program developer by grouping calls passing through an identified question-answer (QA) state or transition into clusters based on causes of problems associated with the calls is provided. The method includes determining a number of clusters into which a plurality of calls will be ... 08/10/06 - 20060178883 - Method of automatically ranking speech dialog states and transitions to aid in performance analysis in speech applications A method of identifying problems in a speech recognition application is provided and includes the step of obtaining a speech application call log containing log data on question-answer (QA) states and transitions. Then, in accordance with the method, for each of a multiple transitions between states, a parameter is generated ... 06/15/06 - 20060129397 - System and method for identifying semantic intent from acoustic information In accordance with one embodiment of the present invention, unanticipated semantic intents are discovered in audio data in an unsupervised manner. For instance, the audio acoustics are clustered based on semantic intent and representative acoustics are chosen for each cluster. The human then need only listen to a small number ... 04/20/06 - 20060085188 - Method for segmenting audio signals An input signal is converted to a feature-space representation. The feature-space representation is projected onto a discriminant subspace using a linear discriminant analysis transform to enhance the separation of feature clusters. Dynamic programming is used to find global changes to derive optimal cluster boundaries. The cluster boundaries are used to ... 01/26/06 - 20060020456 - Object oriented acoustic modeling tools and methods Techniques for creating an acoustic model from a finite element mode include strategically partitioning elements of the finite element model into sets, forming composite centroids from the partitioned elements and then calculating the spatial distances between the composite centroids so that an acoustic model can be created using a tiny ... 10/13/05 - 20050228664 - Refining of segmental boundaries in speech waveforms using contextual-dependent models A method and apparatus are provided for refining segmental boundaries in speech waveforms. Contextual acoustic feature similarities are used as a basis for clustering adjacent phoneme speech units, where each adjacent pair phoneme speech units include a segmental boundary. A refining model is trained for each cluster and used to ... 08/18/05 - 20050182626 - Speaker clustering and adaptation method based on the hmm model variation information and its apparatus for speech recognition A speech recognition method and apparatus perform speaker clustering and speaker adaptation using average model variation information over speakers while analyzing the quantity variation amount and the directional variation amount. In the speaker clustering method, a speaker group model variation is generated based on the model variation between a speaker-independent ... ### FreshPatents.com Support |
