Time Durations of Phonemes in the Polish Language

Statistical phonetic data for Polish were collected. Phonemes are of different lengths, varying from 30 ms to 200 ms. Average phoneme durations are presented. A corpus of spoken Polish was used to collect such statistics from real language to apply it in an automatic speech recognition system. This natural phenomena could be used in speech parametrisation and modelling as an additional source of information for a case of speech segments analysis. The collected data are published in the paper, along with comments on the corpus and the method used. The obtained data were compared with the expected values according to phonetic literature
