Let Siri recognize names of people whose pronunciation differ from spelled name.
Siri is an amazing Voice command software by Apple but no one expected it to be 100% perfect with different kind of names or pronunciations we have. But if you are getting tired of Siri not recognizing to some of your commonly used contact names then don’t worry as there is a feature in Siri with which you can assign a “Phonetic name” to the person in your address book. This way Siri will recognize the person when you pronounce his or her name.
To do this goto address book open the contact whose pronunciation of name doesn’t match spelling of name, then use option of “Add custom Field” and you will get list of options to add detail of your contact in address book. There you will see the new option of “Phonetic first/last name”. You can use these to type the spellings which it will be easier for Siri to understand and recognize the name. Now you will be able to use voice commands to call or sms this person with ease.
Do note that it is being reported that due to some bug, this option is not available on all iPhone 4S models. Even though OS version may be same on two iPhones, but it is still possible that one of them may have this feature and other may not have the Phonetic name field. For such people you just have to wait till Apple releases a bug fix.
