Генератор мата is a free Android app developed by luna-park that generates obscene and vulgar language. The app uses text-to-speech technology to pronounce the generated words or phrases, but an Internet connection is required to use this feature. The app does not contain any advertisements and offers the option to use the built-in TTS engine. You can find the TTS engine settings in the "Settings - Language and Input - Text-to-speech output" menu. If you choose the "Google Text-to-speech engine," make sure that the "Voice Data" for the Russian language is installed. The possible path can be: Settings - Accessibility - Text-to-speech output - (gear icon next to "Google Text-to-speech engine") - Install voice data - Russian (Russia).
