Jed Roberts, James K Baker, Edward W Porter: Method for interactive speech recognition and training. Dragon Systems, Edward W Porter, June 25, 1991: US05027406 (402 worldwide citation)

A method for creating word models for a large vocabulary, natural language dictation system. A user with limited typing skills can create documents with little or no advance training of word models. As the user is dictating, the user speaks a word which may or may not already be in the active vocabu ...

Edward W Porter: Voice recognition system. Dragon Systems, Edward W Porter, May 9, 1989: US04829576 (248 worldwide citation)

A text locating system recognizes spoken utterances, uses the recognized words as a search string, and searches text for words matching that search string. The probability that a given vocabulary word is selected as a search word is altered both by limiting the recognizable vocabulary to words in th ...

A method is provided for deriving acoustic word representations for use in speech recognition. Initial word models are created, each formed of a sequence of acoustic sub-models. The acoustic sub-models from a plurality of word models are clustered, so as to group acoustically similar sub-models from ...

Laurence S Gillick, Robert S Roth: Large-vocabulary continuous speech prefiltering and processing system. Dragon Systems, Lahive & Cockfield, April 13, 1993: US05202952 (198 worldwide citation)

A continuous speech prefiltering system for use in continuous speech recognition computer systems. The speech to be recognized is converted from utterances to frame data sets, which frame data sets are smoothed to generate a smooth frame model over a predetermined number of frames. A resident vocabu ...

James K Baker: Speech recognition using multiple recognizers (selectively) applied to the same input sample. Dragon Systems, Fish & Richardson P C, September 19, 2000: US06122613 (165 worldwide citation)

A speech sample is recognized with a computer system by processing the speech sample with at least two speech recognizers, each of which has a different performance characteristic. One speech recognizer may be a large-vocabulary, continuous speech recognizer optimized for real-time responsiveness an ...

Laurence Gillick, Paul G Bamberg, James K Baker, Robert S Roth: Method for creating and using multiple-word sound models in speech recognition. Dragon Systems, Edward W Porter, June 6, 1989: US04837831 (160 worldwide citation)

A first speech recognition method receives an acoustic description of an utterance to be recognized and scores a portion of that description against each of a plurality of cluster models representing similar sounds from different words. The resulting score for each cluster is used to calculate a wor ...
