  • Method and apparatus for perfoming spoken language translation
    Publication number: 20020198713
    Abstract: A method and an apparatus for performing spoken language translation are provided, wherein a speech input is received comprising at least one source language. The speech input comprises words, sentences, and phrases in a natural spoken language. Source expressions are recognized in the source language. Misrecognitions of the source expressions resulting from factors comprising noise and speaker variation are minimized by the generation of intermediate data structures that encode at least one recognition hypothesis. Furthermore, misrecognitions are minimized by the generation of candidate recognized source expressions by processing the intermediate data structures using models comprising a general language model and a domain model. A recognized source expression is selected and confirmed by a user through a user interface. The recognized source expressions are translated from the source language to a target language, and a speech output is synthesized from the translated target language source expressions.

  • Analyzing inflectional morphology in a spoken language translation system
    Patent number: 6442524
    Abstract: At least one speech input is received and at least one token is generated from speech input. Morphemes of the tokens are reduced to at least one feature. Furthermore, an inflection type of the token is identified. At least one dictionary is searched for entries comprising features that match the features reduced from the morphemes. At least one lexical feature structure is generated for the token by inserting at least one morphological feature associated with the inflection type into the entry feature. An output is provided comprising at least one lexical feature structure.
