Russian טעקסט צו רעדן

אױף Russian טעקסט צו שפּראַך

Russian text-to-speech is dominated by two features the Cyrillic script leaves implicit. First, lexical stress is free and unmarked yet drives meaning (за́мок "castle" vs замо́к "lock"), so the engine relies on a pronunciation lexicon to place it. Second, unstressed vowel reduction (akanye, where unstressed "о" is read as "a") and the systematic devoicing or voicing assimilation of consonant clusters must be applied to sound native. The letter ё is frequently written as plain е, which the synthesizer has to disambiguate. The standard target is the Moscow literary norm used in broadcasting; principal users are audiobook platforms, navigation services like Yandex, and accessibility tools.
