Method for automatic identification for determining the location and the average length of the base period for isolated words

摘要

method of automatic location and determining the average length of the basic regulation for isolated words is such that the time signal tone krtaniowego containing basic periods is given in the first stage, preliminary examination, during which follows automatically from the najdywanie local minima.and the next steps is to reject local minima differ by more than 8% of the amplitude signal, the rejection of minima located at intervals smaller than 2 ms, and check whether there are periods longer than 8 ms, if followed by their rejection, if not through to the next stage, in which the first determination of the average duration of the period of the basic regulation,after rejection periods smaller than 40% of its value in the next step, followed by re calculation of the average duration of base period, after which the rejection periods smaller than 80% of its value in the final stage, followed by the final calculation of the average value of pods tawowego tone krtaniowego.
