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 unitcalculates the scores of words selected by a preliminary word selectorand determines a candidate for a speech recognition result on the basis of the calculated scores. A control unitproduces 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 unit. A reevaluation unitcorrects the word connection relationships one by one. On the basis of the corrected word connection relationships, the control unitdetermines the speech recognition result. A word connection managing unitlimits times allowed for a boundary between words represented by the word connection relationships to be located thereat. A word connection managing unitlimits start times of words preliminarily selected by the preliminary word selector. The present invention can be applied to an interactive system that recognizes an input speech and responds to the speech recognition result.
