Cannot use raw file to create speaker model

[ra2637]

Hi,

I am using a raw audio file to create the speaker model, the code is as following:

            AssetFileDescriptor audioFile = getApplicationContext().getAssets().openFd("raw.wav");

            //Translating from AssetDescriptor to Byte array
            byte[] audio = new byte[(int)audioFile.getLength()];
            audioFile.createInputStream().read(audio);

            // Send audio to the system
            alizeSystem.addAudio(audio);     //only the bytes

            // Train a model with the audio
            System.out.println("Creating speaker model...");
            alizeSystem.createSpeakerModel("speaker1");

The raw.wav file is actually a raw file, I changed the extension to .wav since I put the file in android assets and it only accept some kinds of extensions.

And my alize config file is as following:

distribType         GD
maxLLK              200
minLLK              -200
bigEndian           false
saveMixtureFileFormat       RAW
loadMixtureFileFormat       RAW
loadFeatureFileFormat       RAW
featureServerBufferSize     ALL_FEATURES
featureFilesPath        data/
mixtureFilesPath        data/

MAPAlgo                             MAPOccDep
loadFeatureFileExtension        .prm

After ran the program, I got the exception:

I/System.out: Creating speaker model...
W/System.err: AlizeSpkRec.AlizeException: [ InvalidDataException 0x73732f4c80 ]
W/System.err:   message   = "Wrong number of data"

I traced the FeatureFileReaderRaw.cpp and think it might be the problem of loadFeatureFileVectSize, and add loadFeatureFileVectSize 16 in the config file, and it crashed in addAudio function.

Is there any suggestion that I can do here? Thanks.

I am thinking to close the issue. Since the problem solved after I use the published default config file. Thanks for the default config file, and I'd recommend to explain each fields so other's can modify the config to fit their system. Thanks!
