Bahl Lalit Rai, Brown Peter Fitzhugh, Desouza Peter Vincent, Mercer Robert Leroy: Design and construction of a binary-tree system for language modelling.. Ibm, May 3, 1989: EP0313975-A2 (156 worldwide citation)

In order to determine a next event based upon available data, a binary decision tree is constructed having true or false questions at each node and a probability distribution of the unknown next event based upon available data at each leaf. Starting at the root of the tree, the construction process ...

Brown Peter Fitzhugh, Della Pietra Stephen Andrew, Della Pietra Vincent Joseph, Mercer Robert Leroy, Jelinek Frederick: Speech recognition system for natural language translation.. Ibm, November 24, 1993: EP0570660-A1 (137 worldwide citation)

A speech recognition system displays a source text of one or more words in a source language. The system has an acoustic processor for generating a sequence of coded representations of an utterance to be recognized. The utterance comprises a series of one or more words in a target language different ...

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 ...

The present invention is a system for translating text from a first source language into a second target language. The system assigns probabilities or scores to various target-language translations and then displays or makes otherwise available the highest scoring translations. The source text is fi ...

Bahl Lalit Rai, Brown Peter Fitzhugh, Desouza Peter Vincent, Mercer Robert Leroy: Method and apparatus for the automatic determination of phonological rules as for a continuous speech recognition system.. Ibm, September 19, 1990: EP0387602-A2 (13 worldwide citation)

A continuous speech recognition system includes an automatic phonological rules generator which determines variations in the pronunciation of phonemes based on the context in which they occur. This phonological rules generator associates sequences of labels derived from vocalizations of a training t ...

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 comprising a series of target words, are generated. Each target word has a context comprising at least ...

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 ...

Brown Peter Fitzhugh, de Gennaro Steven Vincent, Desouza Peter Vincent, Epstein Mark Edward: Method and apparatus for generating models of spoken words based on a small number of utterances.. Ibm, April 29, 1992: EP0482395-A2

A method and apparatus for modeling words based on match scores representing (a) the closeness of a match between probabilistic word models and the acoustic features of at least two utterances, and (b) the closeness of a match between word models and the spelling of the word. A match score is calcul ...
