Length of phonemes in a context of their positions in Polish sentences

The paper presents statistical phonetic data of Polish collected from a corpus. Lengths of phonemes vary from 5 ms to 670 ms. Average durations of Polish phonemes are presented as well as an important anomaly of longer phonemes in the end of sentences, which is the main topic of the paper. This observation can be used in speech recognition for automatic insertation of dots and sentence modelling. Data of 45 speakers, 5130 sentences in total, were described and compared with the values taken from the phonetic literature.
