The continuous spectra of Polish voiceless plosive bursts and fricatives, spoken by 3 male voices, were analysed by measuring the level at fa a 300 Hz between 0-..8 kHz in averaged FTTs.The weighted mean, the skeweness and the kurtosis of the spectral shape were calculated and formed the random variables in a trivariate Discriminant Analysis. Depending on the type of phoneme and he speaking voice, an accuracy of classifacation of the individual phonemes varied between 0 and 100 %.

Keywords: speech recognition, plosives, fricatives
