pitch_slpdl

Four methods used for the Kaggle competition "Pitch estimation and voicing detection" of the subject Speech and Language Processing with Deep Learning (SLPDL) from ETSETB, UPC These are four of the methods we tried for the competition. Other ones have been implemented, but with no good results. The cesptrum one is gave the worse results of these three, that is why we only mention it at the paper delivered but we do not present results about it. HSS method and Autocorrelation with preprocessing filters are the ones that have been submited at the end of the competition and that will be evaluated by the 70% left of the test data.
