      Hi Serguei,

      I read am doing an installation where i need to find out if someone is speaking
      a vowel into a microphone and if yes than which one. After trying out sphinx
      which is seems to be a slight overkill for my problem i found MARF and it appears
      to be good for my needs.
      I read the pdf describing all elements of MARF. And based on your
      SpeakerIdent-application i wrote my little program. So far i go everything running.
      the testing part and the recognition part, but the recognition isnt really reliable.
      something between 40 - 50%.
      These are my settings:
      MARF.setPreprocessingMethod(MARF.DUMMY);
      MARF.setFeatureExtractionMethod(MARF.LPC);
      MARF.setClassificationMethod(MARF.NEURAL_NETWORK);
      MARF.setDumpSpectrogram(false);
      MARF.setSampleFormat(MARF.WAV);
      Is there any way to get better results?
      I also need to find out some characteristics of the voice of the talking person,
      like pitch, amplitude etc... i thought that i may can grab some values from
      the LPC but i couldnt find out which value is for the pitch period. Or am i
      wrong here? Could you explain me in just a couple of words how the vector of
      the 20 elements is built up?

      Thanks for an answer

      Vincent
