Introducing Orion AI TTS: What's New in AudiFlo 0.4.620

This is the biggest AudiFlo update we’ve ever released.

We rebuilt major parts of the app around 🧠 Orion — a new on-device AI voice system focused on natural emotional narration, ultra-fast playback, and smooth performance even on low-end Android phones.

And honestly… it no longer sounds like traditional robotic mobile TTS.

✨ What Makes Orion Different?

🧠 Emotional AI Voices

Orion understands punctuation, tone, and sentence emotion automatically during narration. For example, reading “hello... Hello!?” actually sounds emotionally different instead of flat robotic speech.

🎭 More Human Narration

The voices can naturally express human-like conversational nuances, making it the perfect audiobook and text-to-speech reader. These include:

• Hesitation and thought
• Excitement and joy
• Urgency and panic
• Breathing pauses
• Conversational tone
• Emotional reactions

🌍 30+ Languages Supported

Works across books, EPUBs, PDFs, and web articles with automatic multilingual narration. (See the full list of supported languages below).

⚡ Fully Offline AI

No cloud processing. No API dependency. Enjoy lower latency, better privacy, and much faster playback directly on your device.

📖 Massive Speed Improvements

Long chapters now start almost instantly with dramatically smoother chapter transitions, even in massive EPUBs or web novels.

📱 Better on Low-End Devices

Reduced lag, lower memory usage, smoother scrolling, and much better stability overall for a flawless reading experience on older hardware.

🎵 Faster Mini Player + Smoother UI

The entire app now feels significantly more responsive during long reading sessions.

🛠 Tons of Playback Fixes

Fixed skipped words, repeat issues, loading slowdowns, and multiple long-standing playback bugs.

This update genuinely changes how AI narration feels on mobile. We would love feedback from audiobook listeners, TTS users, accessibility users, language learners, and heavy readers.
