The accuracy of the Silent Speech Interpreter varies based on several factors:

• With clear articulation in good lighting conditions, accuracy typically ranges from 85-95%.
• Accuracy improves as the system learns your specific lip movements and speaking patterns.
• Common phrases and words have higher recognition rates compared to rare or technical terms.
• Environmental factors like lighting, camera quality, and face positioning can affect performance.

For best results, we recommend training the system with custom phrases that you use frequently.

Yes, your privacy is a top priority:

• All processing happens locally on your device - no video or audio data is sent to our servers.
• Your custom training data is stored only on your device.
• The app works offline once downloaded, with no internet connection required.
• We do not collect personal data beyond basic anonymous usage statistics (which you can opt out of in settings).

Silent Speech Interpreter works on a wide range of devices:

• Windows PCs (Windows 10 or newer)
• Mac computers (macOS 10.14 or newer)
• iOS devices (iPhone and iPad with iOS 14 or newer)
• Android devices (Android 9.0 or newer)
• Modern web browsers (Chrome, Firefox, Safari, Edge)

For optimal performance, we recommend a device with a good front-facing camera and a relatively recent processor. The system can run on older devices but may experience slower processing speeds.

Yes! One of the key advantages of Silent Speech Interpreter is that it works well in noisy environments. Since the system interprets lip movements and facial expressions rather than audio, background noise doesn't affect its performance.

This makes it particularly useful in:

• Crowded public spaces
• Loud industrial environments
• Concerts and sporting events
• Any situation where speaking aloud would be difficult or inappropriate

To train the Silent Speech Interpreter for improved accuracy:

1. Go to Settings and select the "Training" tab.
2. Click "Add New Phrase" and enter a phrase you commonly use.
3. Follow the on-screen prompts to record yourself silently speaking the phrase multiple times (at least 10 recordings are recommended).
4. Submit the recordings and allow the system to process them.
5. Test the newly trained phrase to confirm improved recognition.

For best results, train phrases in the same lighting conditions and position that you typically use the system in. Regular training with phrases you use often will significantly improve overall accuracy.
