Make Siri Understand
If you're feeling frustrated with Siri not understanding you, then do not feel robo-rejected -- you are not alone. There is one easy option you can choose from the start to make sure Siri understands who you are, and the names of people you are likely to call or text most often.
Obviously the way Siri hears things is phonetic, so a lot of misunderstanding comes from names that are similar, or that do not follow a conventional phonetic pattern. For example, we would know how to pronounce Angelina, but Siri would think of this as An-G-ell-eena. So you need to make some phonetic examples so that she understands who you mean. If you go into your Contacts, click Edit, and then page down to the bottom and tap Add Field, you then get faced with some choices, two of which relate to phonetics - Phonetic First Name & Phonetic Last Name. So in our example here, you would put in the first name field Anjeleena and then Save.
It won't work for all names, and sometimes you'll need to play around with how you've entered the information, but it works in most cases. If you are still having difficulty then you might need to opt for a nickname, or a relationship name (see below).
