NativeVoice: Offline TTS

NativeVoice turns your text into natural-sounding speech — completely on your device.

No internet connection. No account. No cloud servers. Everything happens on your phone, so your text never leaves it.

WHY NATIVEVOICE

Most text-to-speech apps send your text to a server. NativeVoice runs the entire AI speech model locally, which means it works in airplane mode, on the subway, or anywhere without signal — and nothing you type is ever uploaded.

FEATURES

• Works 100% offline — no connection required, ever
• 4 voice styles — two female (F1, F2) and two male (M1, M2)
• 31 languages for correct pronunciation of your text
• Adjustable speed from 0.5x to 2.0x
• Quality control — choose faster generation or higher audio quality
• Export as WAV to share, edit, or use in your own projects
• Clean, modern interface built for Android
• No ads, no sign-up, no data collection

HOW IT WORKS

1. Type or paste your text
2. Pick a voice and the language of your text
3. Adjust speed and quality
4. Tap Generate and listen
5. Save the result as a WAV file

Most sentences are ready in a few seconds.

GREAT FOR

• Listening to notes, articles, and drafts instead of reading them
• Voiceovers for videos, presentations, and tutorials
• Practising pronunciation and language learning
• Accessibility and reading support
• Proofreading — hearing your own writing catches mistakes
• Anyone who needs speech generation without sending data to the cloud

PRIVACY

• No network access needed for speech generation
• No analytics, no trackers, no advertising SDKs
• Your text and audio stay on your device

FREE AND PREMIUM

Generating and listening to speech is free and unlimited. A one-time purchase or an optional subscription unlocks WAV export so you can save and share your audio.

GOOD TO KNOW

• Requires Android 8.0 or higher
• The speech models are bundled with the app, so the install is large (~500 MB of free storage recommended)
• 2 GB RAM or more recommended
• Speech is produced by an AI model. All audio generated by this app is machine-generated.
