# Local TTS - Voice Aloud Reader

> Local TTS is an offline neural text-to-speech (TTS) app for iPhone and iPad by Rich Soft Co., Ltd. It uses Supertonic 3 and Kokoro-82M to turn PDFs, EPUB e-books, Word documents, articles, notes, and scanned printed pages into natural speech — entirely on-device. Supertonic 3 powers one multilingual voice, offered in ten selectable styles, that reads all 31 languages; Kokoro-82M powers 28 American and British English voices. The voice picker lists 38 entries in total. No internet connection, no accounts, no ads, no tracking; nothing the user reads or listens to ever leaves the device.
