I haven't used Siri that much, but I am also wondering if you could train Siri to learn a users specific pronunciation. I have an odd mixture of accents and there are some words it just never gets right.
Can you correct it in the notes? iOS should learn it
According to the help app in my phone, you should be able to say "Siri, that is not how you pronounce (whatever word) and Siri should ask how it should be pronounced. That's an easier way to fix it.Teaching Siri to spell
When you ask Siri to call your contact you get a reply that it can not find "Contacts Name (the way Siri heard it )" in your contact list.
Do the following after writing down the way Siri thinks it should be spelled.
Go into contacts.
Go to the contact you are working with.
Go into "Edit"
Scroll down to "Add Field" and go into add field.
Go into "Phonetic First Name"
Spell in this field the way that Siri spelled the contact name that you wrote down.
Now Siri will recognize your contact the way you say it. Siri will also spell it correctly now.
