DiarTK tools

This README file explains, in brief, the commands tocompile and run the IB diarization toolkit.

There are three prerequisites to the package

1. Cmake -- required to build the package
2. libboost -- boost library for C++
3. openmp library -- for multithreaded processing

$> cd src/diarization/cmake/$> cmake .$> # make clean if cmake has already been run once$> make

$> # cd to$IB_DIARIZATION_HOME$> bash scripts/run.diarizeme.sh ipfile scpfile opfolder fileid [betaval]

Example command

$> bash scripts/run.diarizeme.sh data/mfcc/AMI_20050204-1206.fea data/scp/AMI_20050204-1206.scp result.dir/ AMI_20050204-1206

To test the result use md-perl-eval tool available on the NIST website

$> perl md-eval-v21.pl -m -afc -c 0.25 -r data/rttm/AMI_20050204-1206.rttm -s result.dir/AMI_20050204-1206.rttm

The expected DER is 8.79%

To add TDOA features, use the following script

$>bash scripts/run.diarizeme.tdoa.sh data/mfcc/$AMI_20050204-1206.fea 0.8 data/tdoa/$AMI_20050204-1206.fea 0.2 data/scp/$AMI_20050204-1206.scp result.dir.tdoa $AMI_20050204-1206

The expected DER is 7.12%
