Description
Experience high-quality, private, and fully offline text-to-speech with Supertonic TTS.
Supertonic TTS is a modern, high-performance speech synthesis engine designed for users who value privacy and speed. Unlike traditional TTS services that rely on the cloud, Supertonic performs all processing locally on your device. Powered by a native Rust backend and ONNX Runtime, it delivers lightning-fast synthesis without ever sending your data to a server.
KEY FEATURES:
* 100% Offline & Private: Your text and generated audio never leave your device. No internet required for synthesis, no tracking, and no data collection. * System-Wide Integration: Use Supertonic as your default Android Text-to-Speech engine. It works seamlessly with your favorite e-readers, navigation apps, and accessibility tools. * High-Performance Core: Built with a native Rust backend and optimized ONNX models for high-quality audio with minimal latency. * Built-in E-book Reader: Listen to your favorite books directly within the app. Supports popular formats like EPUB and PDF via the integrated Readium toolkit. * Custom Pronunciation (Lexicon): Take control of how words are spoken. Define your own pronunciation rules for names, acronyms, or technical jargon. * Audio Export: Save any synthesized text as high-quality WAV files for use in other projects or offline listening. * Material Design 3: A clean, modern, and adaptive interface built with Jetpack Compose that looks great on any device. TECHNICAL EXCELLENCE: Supertonic leverages industry-standard ONNX models for state-of-the-art voice quality. By combining the safety and speed of Rust with the flexibility of Jetpack Compose, Supertonic provides a premium TTS experience that is both powerful and battery-efficient.
OPEN SOURCE: Supertonic TTS is open-source software. We believe in transparency and community-driven development.
