How can I execute OpenSMILE toolkit from Matlab environment?

Question

I want to use the OpenSMILE toolkit as a voice feature extractor. But I developed my project scripts in the Matlab environment. So, I am searching for a way to calling OpenSMILE from Matlab and handle the features obtained. I would be pleased if anybody guides me on this matter.

OpenSMILE script sample that can be executed in windows CMD environment:

SMILExtract_Release.exe -C config/MFCC.conf -I a.wav -O a.HTK

Answer 1

I found a very simple way to do this. After installing the OpenSMILE, this program can be accessed through the CMD environment. That's why I wrote the following function in MATLAB and ran OpenSMILE through it.

function featureSet = OpenSmileFE_MFCC(filePath,fileName)

% make result file name
resultName  = [fileName,'_MFCC.HTK'];

% make OpenSmile Command
comD =['SMILExtract_Release.exe -C config/MFCC12_E_D_A_Z.conf -I ',filePath,... 
'-O ', resultName , '  -noconsoleoutput'];


% excute command
system(comD);
[ features, sampPeriod, parmKind ] = readhtk_lite( resultName );

you can also find the readhtk_lite function script in this link. you can also remove -noconsoleoutput option from the command as below to see the execution detail.

comD =['SMILExtract_Release.exe -C config/MFCC12_E_D_A_Z.conf -I ',filePath,... 
'-O ', resultName ];
