Czech represents a language with a high correlation between phonological and phonetic voicing, but the perception of the voicing contrast is supported by other phonetic correlates. We employed electropalatography (EPG) to investigate the articulatory correlates of the voicing contrast in phonated and whispered speech. Eight subjects read short sentences and VCV sequences with alveolar/ postalveolar fricatives as target sounds. The results revealed significant differences in the contact patterns of fortis (voiceless) and lenis (voiced) fricatives in phonated speech but the differences diminished in whisper. Implications of these findings are discussed with respect to general phonetic theory.
