function epdFileCheck(auSet, speaker)
% epdFileCheck: Check each file after EPD
%
%	Usage:
%		epdFileCheck(auSet)
%		epdFileCheck(auSet, speaker)
%
%	Description:
%		epdFileCheck(auSet) check each audio (from the badly performed ones) in auSet by displaying its endpoints
%			auSet: a structure array of an audio set (See the following example as how to obtain the array)
%
%	Example:
%		auDir='waveFile';
%		fprintf('Reading audio files from %s...\n', auDir);
%		auSet=epdAuSetRead(auDir);
%		epdOpt=myEpdOptSet;
%		[recogRate, auSet2]=epdPerfEval(auSet, epdOpt);
%		epdFileCheck(auSet2);
