To convert a voice the following steps are neccessary:

If you want to use Praat as pitch tracker:

• Praat PraatToPitchMarks.praat Source.wav PitchMarksPraat.PointProcess
• perl convertPraatToMatlab.pl PitchMarksPraat.PointProcess PitchMarksMat.txt
• in octave: vc('Source.wav', alpha, fRatio, 'Output.wav', 'PitchMarksMat.txt') (alpha is the warping factor, fRatio is the ratio of the fundamental frequency for psola)

If you want to use the integrated pitch tracker:

• in octave: vc('Source.wav', alpha, fRatio, 'Output.wav') (alpha is the warping factor, fRatio is the ratio of the fundamental frequency for psola)
