It would be very helpful, if by voice you could open your phone. The phone would open by saying Hey Google open my phone, Hey Bixby open my phone, or by speaking your password and the phone opens.
You can't be serious, this would make your phone really insecure! Who would want to share their password out loud? If you're just looking for this for your home, there are trusted places where you can unlock it for a long time!
