| Abstract(in English) | Telephone conversation retrieval systems are required for mail order, help desk and similar telecommunications services. The researches of spoken term detection are drove using strong language model. However it is difficult to construct the language model of telephone conversations. In such case, word spotting can be used. In conventional word spotting, for exsample, continuous dynamic programming (DP) can be appled. This report proposes a new method in order to realize telephone conversation log retrieval. The method is structured by distance matrix images (DMI) and the Hough transform of DMI. Important parameters are threshold values for binalizing of DMI and voting of Hough transfom. The merit of this method is not to need a dictionary and the detailed language model. This report shows that the evaluation method and the result that indicates the advatages of the new method compared with the conventional method, the continuous DP. |
