A method, apparatus, and medium for generating a grammar network for speech recognition and a dialogue speech recognition are provided. A method, apparatus, and medium for employing the same are provided. The apparatus for generating a grammar network for speech recognition includes: a dialogue history storage unit storing a dialogue history between a system and a user; a semantic map formed by clustering words forming each dialogue sentence included in a dialogue sentence corpus depending on semantic correlation, and generating a first candidate group formed of a plurality of words having the semantic correlation extracted for each word forming a dialogue sentence provided from the dialogue history storage unit; a sound map formed by clustering words forming each dialogue sentence included in the dialogue sentence corpus depending on acoustic similarity, and generating a second candidate group formed of a plurality of words having an acoustic similarity extracted for each word forming the dialogue sentence provided from the dialogue history storage unit and each word of the first candidate group; and a grammar network construction unit constructing a grammar network by combining the first candidate group and the second candidate group.

Apparatus, method, and medium for generating grammar network for use in speech recognition and dialogue speech recognition

A method and apparatus for determining the possibility of pattern recognition of time series signal independent of a pattern recognition ratio is provided. The method for determining the possibility of pattern recognition of time series signal includes extracting a time forward feature and a time reversed feature from an input signal having a time series pattern, generating time forward alignment and time reversed alignment by using the time forward feature and the time reversed feature, comparing the time forward alignment with the time reversed alignment to compute a likelihood of pattern recognition, and determining that the input signal can be recognized if the likelihood is larger than a predetermined threshold value. The possibility of the pattern recognition of the whole system can be determined, independent of the pattern recognition capability of each of the pattern recognition models, by extracting the patterns from the time series signal by using the plurality of the pattern recognition models and then obtaining the likelihood between the patterns to compare the likelihood with the threshold value. In addition, the pattern recognition can be performed in the non-limited environment.
