Inputting nicknames
Siri is one of the most useful virtual assistants out there. Using her services, you can quickly make calls, type messages with voice command, and open up all sorts of apps. If you want Siri to send a message to someone, all you need to do is tell her in clear, plain English.
But instead of mentioning the complete name of the contact, you can define nicknames for your loved ones. Open up the contact card, tap on Edit, tap on Add Field, then choose Nickname. You don’t have to use this feature for each and every contact card, just the ones you communicate with most frequently.
