Abstract:
1. A language understanding device comprising: a language understanding model storing unit configured to store, as a language understanding model, word transition data, filler transition data and concept weighting data, a finite state transducer processing unit configured to output understanding result candidates based on words included in a word sequence being input which is obtained by a speech recognition process and present states, the finite state transducer processing unit is further configured to accumulate filler weights in accordance with the filler transition data read out from the language understanding model storing unit a concept weighting processing unit configured to accumulate concept weights, an understanding result determination unit configured to determine an understanding result from the understanding result candidates based on the cumulative word weight, the cumulative filler weight and the cumulative concept weight for each understanding result candidate, wherein the understanding result determination unit is configured to determine the understanding result as the understanding result candidate having a highest value for a summed cumulative word weight, cumulative filler weight and cumulative concept weight.
