International Business Machines Corporation, Marc D Schechter, November 30, 1993: US05267345 (178 worldwide citation)

A language generator for a speech recognition apparatus scores a word-series hypothesis by combining individual scores for each word in the hypothesis. The hypothesis score for a single word comprises a combination of the estimated conditional probability of occurrence of a first class of words comp ...

International Business Machines Corporation, Marc D Schechter, Robert P Tassinari, April 23, 1996: US05510981 (170 worldwide citation)

An apparatus for translating a series of source words in a first language to a series of target words in a second language. For an input series of source words, at least two target hypotheses, each including a series of target words, are generated. Each target word has a context comprising at least ...

Doped silica glass can be manufactured by reacting gaseous vapors of silica-forming compounds and dopant-forming compounds. Increased fluorine dopant can be provided with less fluorine dopant-forming compound, when the fluorine dopant-forming compound is hexafluoroethane (C.sub.2 F.sub.6).

Masafumi Nishimura: Speech recognition system using Markov models having independent label output sets. International Business Machines Corporation, Marc D Schechter, July 9, 1991: US05031217 (167 worldwide citation)

A speech recognition system measures the values of at least two classes of features of an utterance: (1) a first class whose value is related to the frequency spectrum of the utterance, and (2) a second class whose value is related to the variation with time of the "first class" value of the utteran ...

Peter F Brown, Peter V De Souza, David Nahomoo, Michael A Picheny: Automatic determination of labels and Markov word models in a speech recognition system. International Business Machines Corporation, Marc D Schechter, December 10, 1991: US05072452 (166 worldwide citation)

In a Markov model speech recognition system, an acoustic processor generates one label after another selected from an alphabet of labels. Each vocabulary word is represented as a baseform constructed of a sequence of Markov models. Each Markov model is stored in a computer memory as (a) a plurality ...

A speech coding and speech recognition apparatus. The value of at least one feature of an utterance is measured over each of a series of successive time intervals to produce a series of feature vector signals. The closeness of the feature value of each feature vector signal to the parameter value of ...

Masafumi Nishimura, Masaaki Okochi: Speech recognition by concatenating fenonic allophone hidden Markov models in parallel among subwords. International Business Machines Corporation, Marc D Schechter, Robert P Tassinari Jr, March 26, 1996: US05502791 (155 worldwide citation)

Analysis of a word input from a speech input device 1 for its features is made by a feature extractor 4 to obtain a feature vector sequence corresponding to said word, or to obtain a label sequence by applying a further transformation in a labeler 8. Fenonic hidden Markov models for speech transform ...
