How do you know IPA pronunciation?

Hey Slp1, how do you know the IPA pronunciation? I would like to help by adding pronunciations as opposed to just adding the templates, but I don't know how to find out the pronuncations (like for 'Ewa Beach) or how to transcribe them into IPA. Thanks! Iamunknown 

 I learnt IPA during phonetics courses at university.  If you want to learn IPA then a course is probably the best plan, but otherwise there are books as well as  articles and exercises on the internet (including wikipedia).  It is worth training yourself to really listen and feel words a bit, as it is so easy to get misled by the spelling in English.  I hope this helps.
