CLVCA (Cross-Language Voice Chat Application) is an offline AI-powered communication app designed for real-time translation between nearby devices.
Voice Recognition & Output
Understand how CLVCA processes your speech and generates audio.
Speech-to-Text (STT): Translation works 100% offline, but high-accuracy voice recognition depends on your device's native engine. Some devices may require a one-time internet connection to verify voice data.
Silent Output (TTS): CLVCA uses the Flutter TTS engine. If you hear no sound, please ensure "Speech Services by Google" is set as your default engine in your Phone Settings.
Regional Accents: You can customize speaking speed, pitch, and regional accents in Settings > Voice & Audio.
P2P Connectivity
Connect with nearby friends without using cellular data or the internet.
How to Link: One user must "Start Hosting" while the other selects "Join Friend."
Scanning QR: For instant pairing, ask your friend to scan the QR code displayed on the Host's screen.
Effective Range: Maintain a distance of 10-15 meters for a stable Bluetooth/Wi-Fi connection.
Privacy Promise
Your privacy is built into the core of CLVCA.
On-Device Processing: CLVCA does not upload your personal voice data to any server. All processing happens locally on your hardware.
History Control: You can permanently delete your conversation logs by selecting "Clear All History" in the History screen.
Cache Reset: Logging out or clearing app data in Settings will reset your configurations and temporary cache.
