Apparatus and method for using user context information to improve N-best processing in the presence of speech recognition uncertainty

摘要

The present invention provides a method and apparatus for using user-context information to improve N-best processing in the presence of speech recognition uncertainty. Once digitized voice data is received, the voice data is processed by a speech recognizer to determine one or more phrases recognized as the digitized voice data provided by the user based on the currently active recognition grammar. When more than one phrase is recognized as the digitized voice data provided by the user as a result of voice recognition uncertainty, user-specific context information is used to choose a recognized phrase from the one or more phrases recognized as the digitized voice data.
