Abstract in different language: This paper represents another step towards the linguistic naturalness of synthetic Czech. Its main goal is to eliminate undesirable occurrences of the so-called parasitic speechsounds, specifically preglottalization, from synthesized speech. After explaining the nature of parasitic speechsounds in Czech, we present procedures for both automatic detection and segmentation of these sounds in the source speech recordings. The main contribution of this paper consists in the proposal and implementation of two ways of synthesizing speech without preglottalization---cutting the parasitic sound from the signal and penalizing preglottalization during unit selection. Both these ways succeeded in suppressing the intrusiveness of preglottalization, with the latter method being evaluated as superior.
