% Main program for generating the PV files for evaluation.
% To distinguish from GT, these PV files have extension of "pv2".

% ====== Add necessary toolboxes to the search path
toolboxDir='d:/users/jang/matlab/toolbox/';
addpath([toolboxDir, 'utility']);
addpath([toolboxDir, 'sap']);

% ====== Define the directory of the wave files to be tested
auDir='audioWithoutGt';			% Replace this with the recordings of this year, which contains audio files without PV files
outputPvDir='b00902024_pv2';	% All the generated PV files are put here, so you can compress the folder for upload. Please follow the convention of "studentID_pv2".

% ====== Read wave files and the corresponding PV files (if exist)
fprintf('Read wave files from "%s"...\n', auDir);
auSet=ptAuSetRead(auDir);
fprintf('Collected %d wave files,\n', length(auSet));
if isempty(auSet), error('Cannot read any wave files from the given directory "%s"!\n', auDir); end

% ====== Compute predicted pitch and save pv files for further performance evaluation
ptOpt=myPtOptSet;
[recogRate, auSet, time]=ptPerfEval(auSet, ptOpt);
fprintf('Overall recognition rate = %.2f%%\n', recogRate*100);
fprintf('Overall time for %d files = %g sec\n', length(auSet), time);
fprintf('Average time per file = %g sec\n', mean([auSet.time]));

%% ====== Write pv files to output folder
%outputPvPath=[tempdir, outputPvDir];
outputPvPath=outputPvDir;
if ~exist(outputPvPath, 'dir')
	fprintf('Creating output directory: %s\n', outputPvPath);
	[status, message, messageid]=mkdir('.', outputPvPath);
end
