Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we propose a 19-channel microphone array recording system used for blind speech extraction and diarization with image information to make speech archives of poster session.
This system realizes noise reduction of 8.9 dB to 34.0 dB under the conditions of cepstral distortion of 4.9 dB to 6.6 dB when a presenter is extracted, and noise reduction of 4.6 dB to 10.1 dB under the conditions of cepstral distortion of 6.0 dB to 8.1 dB when a questioner is extracted.
Also, it is revealed that the system's diarization accuracy corresponds to {\itshape F-measure} of 0.99 when a presenter is extracted and {\itshape F-measure} of 0.88 when a questioner is extracted.
