1. To increase recognition success rate, consider using full name

   (1) if John Smith is registered on the phone, it is better to say "Call John Smith" than saying "Call John" only

2. Use the same name registered on the phone

   (1) H/U will not recognize different name stored on the phone. For example, saving mother as "Cindy" on the phone and use voice command mom or mother to call
