Voice MegaGen is a versatile app that transforms text into realistic speech using Google Gemini neural technology and turns your device into a powerful full-screen digital sign. Whether you need natural voice playback or a bold on-screen message, everything is built into one elegant interface.

AI Voice Generator

Type any text up to 500 characters and instantly generate natural-sounding speech. Choose from 30 distinctive AI voices, each with its own personality — from warm and expressive to deep and mysterious. Every voice is clearly labeled and searchable by name, making selection fast and intuitive.

Listen to generated audio directly inside the app and create high-quality voice clips in seconds. Each clip is saved locally on your device in WAV format, allowing you to replay or manage recordings anytime.

Full-Screen Sign Display

Turn your iPhone or iPad into a stylish digital sign. Enter your message, adjust font size from 32 to 140 pt, and choose from six atmospheric backgrounds: Dark, Navy, Forest, Wine, Charcoal, or Midnight.

When activated, the app automatically switches to landscape mode and hides system elements, delivering a clean, distraction-free full-screen display. Perfect for airport pickups, events, cafes, presentations, or quick announcements.

Generation History

All created voice clips are stored locally on your device. Access previous recordings instantly, play them with a single tap, or remove them with a swipe. The home screen displays useful statistics including total clips created, combined audio duration, and number of saved favorites.
