ABSTRACT:
The present invention provides a speech recognition apparatus having high speech recognition performance and capable of performing speech recognition in a highly efficient manner. A matching unit14calculates the scores of words selected by a preliminary word selector13and determines a candidate for a speech recognition result on the basis of the calculated scores. A control unit11produces word connection relationships among words included in a word series employed as a candidate for the speech recognition result and stores them into a word connection information storage unit16. A reevaluation unit15corrects the word connection relationships one by one. On the basis of the corrected word connection relationships, the control unit11determines the speech recognition result. A word connection managing unit21limits times allowed for a boundary between words represented by the word connection relationships to be located thereat. A word connection managing unit22limits start times of words preliminarily selected by the preliminary word selector13. The present invention can be applied to an interactive system that recognizes an input speech and responds to the speech recognition result.
