Tel-Trans

[App Overview]
"Tel-Trans" is an advanced AI multilingual voice interpretation and calling app designed to completely eliminate language barriers. Simply scan a QR code with your smartphone or tap a button within the app to instantly begin smooth multilingual voice conversations and interpretation calls with people around the world.

[Main Features]
1. Extensive Multilingual Support: Covers 90 Unique Languages ​​and 279 Locales
Supports a total of 279 locales (including 149 Microsoft Speech Service locales and 130 Web Speech API locales), encompassing major languages ​​such as English, Chinese, and Korean, as well as dialects and regional variations.

2. High-Precision Hybrid Speech Recognition Engine
Employs a hybrid recognition method combining the browser's standard "Web Speech API" with the advanced AI cloud "Microsoft Speech Service (Azure)." Even in noisy environments or with diverse accents, it accurately understands speech and provides real-time interpretation.

3. Secure and Reliable Security Design
Privacy protection is our top priority; no call audio or session data is stored on the server. All communications are encrypted using strong HTTPS.
Furthermore, the app securely stores up to 10 session histories only in your device's local environment (DataStore), allowing you to safely review past history.

4. No Troublesome Registration or Complex Settings Required
The app itself operates simply as a "translation session launcher." The app never requests sensitive smartphone permissions such as microphone or location information. Actual call and translation processing is completed within a secure built-in browser (Chrome Custom Tabs), so you can use it safely immediately after installation.
