Russian TTS audio on tts.audio runs on two MAI Voice 2 voices: Lev (male) and Masha (female). Both produce Standard Russian, the Moscow-based variety used in Russian broadcast media, literature, and government communication, and understood by Russian speakers across Russia, Belarus, Kazakhstan, Kyrgyzstan, and the broader diaspora. Lev and Masha both support thirteen expressive styles (adventurous, caring, curious, empathetic, encouraging, friendly, cheerful, excited, nostalgic, reflective, sad, disappointed, serious). Use cases for Russian TTS include Russian-language YouTube voiceovers, e-learning localization, accessibility audio for Russian-language documentation, audiobook drafts, and pronunciation reference for English-speaking learners of Russian. PDF upload handles the Cyrillic alphabet natively, including the letters ё, й, ъ, ь, and the hard/soft sign distinction that affects pronunciation of the preceding consonant.
