Tentang Czech teks ke pertuturan

Czech text-to-speech has to handle one of the densest consonant systems in Europe — syllables can be built entirely from consonants, as in the famous tongue-twister "strč prst skrz krk" ("stick a finger through the throat"), where r and l act as syllable nuclei. The language relies on diacritics: the háček (ř, š, č, ž, ě) and the acute accent that marks long vowels (á, é, í, ó, ú/ů), all phonemic, so a model must treat "byt" (flat) and "být" (to be) as different words. The notorious letter ř — a raised alveolar trill found in almost no other language — is a true test of synthesis quality, as is the regular but strong fixed stress on the first syllable of each word. Czech orthography is highly phonemic, which helps grapheme-to-phoneme conversion, but voicing assimilation across consonant clusters and at word boundaries still has to be modeled for the output to sound fluent.
