It is thought that an auditory preprocessing organ called cochlea has the function. Therefore, this study mimics an attenuation of sound by lymph fluid in the cochlea using a multiresolution by discrete wavelet transform. In our previous study, a vowel and consonant recognition system and these FPGA implementation have been independently created to mimic the complex processing of the cochlea. In this study, we construct a speech recognition system integrated with the vowel and consonant recognition system. In order to show its effectiveness, we verify the circuit size and recognition rate of the proposed system.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムLSI設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-01-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2012-SLDM-154"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":80269,"updated":"2025-01-21T19:52:13.262226+00:00","links":{},"created":"2025-01-18T23:34:46.810466+00:00"}
