Our app utilizes advanced large-scale AI translation technology, supporting multilingual translation, speech error correction, and high-quality localized outputs. To ensure the best results:

1. Maintain a stable network connection.
2. Verify that the language settings for both parties are correctly configured.
3. Speak clearly and close to the microphone for optimal audio input.

For the highest translation quality, we recommend using the app in a quiet environment.

Our AI-powered translation delivers near-instant results:

• 📞 Phone Calls: ~0.8-1.2s latency (optimized for fluid conversations)
• 👥 Face-to-Face: ~1.0-1.5s (with contextual analysis)

Both modes leverage our sub-second AI engine, with phone calls achieving faster speeds through dedicated network optimization.

Note: Speeds may vary slightly by network conditions.
