Abstract (in Japanese) (See Japanese page) 
(in English) Telephone conversation retrieval systems are required for mail order, help desk and various telecommunications services. However, it is difficult to construct the language model and to overcome ambiguous pronunciation.
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 line detection in the images. Important parameters are threshold values for binalizing of DMI. The merit of this method is not to need a dictionary and the detailed language model.
This report shows the reason of the advantages against the conventional continuous DP matching proving by experimental method using the difference of the standard deviation of the the number of votes in Hough Transform.
