In this paper a method of separating the overlapping speech events by using an adaptive beamforming ABF framework is proposed. The main feature of this method is that all the information necessary for the adaptation of ABF including microphone calibration is obtained from meeting recordings based on the results of speech-event detection. The performance of the separation is evaluated via ASR using real meeting recordings. Copyright 2007 Futoshi Asano et al.

INTRODUCTION The analysis structuring and automatic transcription of meeting recordings have attracted considerable attention in recent years . 1-5 . Especially for small informal meetings a major difficulty is that the discussion consists of spontaneous speech and various types of unexpected speech or nonspeech events may occur. One such event is the responses by listeners such as Uh-huh or I see being inserted in short pauses in the main
