ActiveUS7805299B2Improve accuracyEasy to identifySpeech recognitionDigital dataSpeech identification
A virtual vocabulary database is provided for use with a with a particular user database as part of a speech recognition system. Vocabulary elements within the virtual database are imported from the user database and are tagged to include numerical data corresponding to the historical use of the vocabulary element within the user database. For each speech input, potential vocabulary element matches from the speech recognition system are provided to the virtual database software which creates virtual sub-vocabularies from the criteria according to predefined criteria templates. The software then applies vocabulary element weighting adjustments according to the virtual sub-vocabulary weightings and applies the adjustment to the default weighting provided by the speech recognition system. The modified weightings are returned with the associated vocabulary elements to the speech engine for selection of an appropriate match to the input speech.

ActiveUS7426468B2Improve accuracyImprove speech recognition performanceSpeech recognitionSpeech identificationSpeech input
The present invention involves the dynamic loading and unloading of relatively small text-string vocabularies within a speech recognition system. In one embodiment, sub-databases of high likelihood text strings are created and prioritized such that those text strings are made available within definable portions of computer-transcribed dictations as a first-pass vocabulary for text matches. Failing a match within the first-pass vocabulary, the voice recognition software attempts to match the speech input to text strings within a more general vocabulary. In another embodiment, the first-pass text string vocabularies are organized and prioritized and loaded in relation to specific fields within an electronic form, specific users of the system and / or other general context-based, interrelationships of the data that provide a higher probability of text string matches then those otherwise provided by commercially available speech recognition systems and their general vocabulary databases.

Method and apparatus for performing speech recognition utilizing a supplementary lexicon of frequently used orthographies
InactiveUS6018708AImprove recognition accuracyAutomatic exchangesSpeech recognitionSpeech identificationSpeech sound
The invention relates to a method and an apparatus for recognising speech, more particularly to a speech recognition system and method utilising a speech recognition dictionary supplemented by a lexicon containing frequently occurring word sequences (orthographies). In typical speech recognition systems, the process of speech recognition consists of scanning the vocabulary database or dictionary by using a fast match algorithm to find the top N candidates that potentially match the input speech. In a second pass the N candidates are re-scored using more precise likelihood computations. The novel method comprises the introduction of a step in the search stage that consists of forcing the insertion in the list of N candidates entries selected from a lexicon containing frequently used orthographies to increase the probability of occurrence of certain text combinations.

Method and system for naming a cluster of words and phrases
The present invention provides a method, system and computer program for naming a cluster, or a hierarchy of clusters, of words and phrases that have been extracted from a set of documents. The invention takes these clusters as the input and generates appropriate labels for the clusters using a lexical database. Naming involves first finding out all possible word senses for all the words in the cluster, using the lexical database; and then augmenting each word sense with words that are semantically similar to that word sense to form respective definition vectors. Thereafter, word sense disambiguation is done to find out the most relevant sense for each word. Definition vectors are clustered into groups. Each group represents a concept. These concepts are thereafter ranked based on their support. Finally, a pre-specified number of words and phrases from the definition vectors of the dominant concepts are selected as labels, based on their generality in the lexical database. Therefore, the labels may not necessarily consist of the original words in the cluster. A hierarchy of clusters is named in a recursive fashion starting from leaf clusters. Dominant concepts in child clusters are propagated into their parent to reduce the labeling complexity of parent clusters.

Techniques for relating data stored in one or more storage systems for an enterprise include managing information chunks in one or more storage systems. Each chunk comprises a unit of data for storage and retrieval operations. The techniques also include managing a vocabulary database. The vocabulary database includes data structures describing atomic concepts among names in an enterprise-specific vocabulary and data structures describing relationships among the atomic concepts. Content in a document is arranged based at least in part on data in the vocabulary database. The content is based at least in part on an information object or “chunk” in the storage system. Thus, content originally unrelated and authored over time by many different persons and organizations can be related using the business vocabulary concepts and relationships in the vocabulary database.
