Abstract (in Japanese) (See Japanese page) 
(in English) It is important for efficiently reviewing meeting speech archives to preliminarily and automatically detect "when, how and who talked". In this paper, we propose a method for automatically detecting a shortand scattered signal such as agreements by using only acoustical
information. The proposed method has two steps: 1) extract a spatial power spectrum frame-by-frame from the meeting speech archive recorded by a microphone array, and 2) detect the target signal by using an outlier detection algorithm based on principal component analysis. To evaluate the effectiveness of the proposed method, we conducted an experiment using the meeting speech archive recorded in a real
room. The experimental results imply that we can detect a long utterance, a short utterance, no utterance from only a few principal components.
