In order to localize talker direction exactly in low SNR conditions, a talker localization algorithm based on extracting a pitch harmonics is used. To evaluate the performance of the proposed method, the speech recognition experiments are carried out both in simulation and in an experimental room. These results show that the proposed method attains the higher talker localization accuracy and word recognition accuracy than a conventional method.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_publisher_10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_7_rights_11":{"attribute_name":"出版者URL","attribute_value_mlt":[{"subitem_rights":"http://ci.nii.ac.jp/naid/110002722138"}]},"item_7_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 1998 情報処理学会.","subitem_rights_language":"ja"},{"subitem_rights":"ここに掲載した著作物の利用に関する注意: 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。","subitem_rights_language":"ja"},{"subitem_rights":"Notice for the use of this material: The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
