Hi there @francesca.coppola, and welcome to the community,
For better accuracy, you can now only register your face to AIBI through the app — not through voice commands.
Tips for Better Face Registration:
• Make sure the area is well-lit
• 
Hold AIBI about 1 foot (12 inches) away from your face
• 
Keep your face clearly visible and steady
This helps AIBI recognize you more accurately.
Steps to Register Your Face:
• 
Open the AIBI Pocket App
• 
Tap “Meet AIBI”
• 
Select “Add New”
• 
Enter your name
• 
Tap “OK”
• 
AIBI will scan your face
Once your face is successfully registered
If not successful.
