  • Patent number: 7996218
    Abstract: A user adaptive speech recognition method and apparatus is disclosed that controls user confirmation of a recognition candidate using a new threshold value adapted to a user. The user adaptive speech recognition method includes calculating a confidence score of a recognition candidate according to the result of speech recognition, setting a new threshold value adapted to the user based on a result of user confirmation of the recognition candidate and the confidence score of the recognition candidate, and outputting a corresponding recognition candidate as a result of the speech recognition if the calculated confidence score is higher than the new threshold value. Thus, the need for user confirmation of the result of speech recognition is reduced and the probability of speech recognition success is increased.

  • Patent number: 7953594
    Abstract: A method and an apparatus for selecting a vocabulary closest to an input speech from among lexicons stored in memory, wherein a centroid lexicon representing lexicons belonging to a predetermined lexicon group is generated. Two lexicons, having a longest distance therebetween in the lexicon group, are selected using the centroid lexicon from the lexicon group, and a node indicating the lexicon group branches based on the two selected lexicons. A node having low group similarity is selected from among current terminal nodes, including branch nodes, and the above procedure is repeatedly performed on a lexicon group indicated by the selected node.

  • Patent number: 7369995
    Abstract: A speech synthesis method, in which speech units are concatenated using a DB, wherein the speech units to be concatenated are determined and divided into a left speech unit and a right speech unit. The length of an interpolation region of each of the left and right speech units is variably determined. An extension is attached to a right boundary of the left speech unit and an extension to a left boundary of the right speech unit. The locations of pitch marks included in the extension of each of the left and right speech units are aligned so that the pitch marks can fit in the predetermined interpolation region. The left and right speech units are superimposed after fading out the left speech unit and fading in the right speech unit. Accordingly, a determination of whether extra-segmental data exists or not is made, and smoothing concatenation is performed using either an interpolation of existing data or an interpolation of extrapolated data depending on the result of the determination.
