Yup, that seems to work fine on forum, LingQ, vocabulary page and flashcard 
Are you transcribing your own speech there?
Helen, do you have a special font on your computer that allows you to type IPA symbols? Or how else did you type that sentence?
I used an automatic transcriber, but it looks to me to be the same as my own speech. English Phonetic Transcription.
I also found this “virtual keyboard” for IPA: Type IPA phonetic symbols - online keyboard (all languages)
Ah, that would a grand coincidence if it were indeed the same as your own speech…unless you do indeed speak a ‘northern/north midland American dialect.’ 
When I studied phonetics, I used a book written for American speakers first and it would note the RP pronunciation too. As an Australian, I had to work out all the right vowels for myself. Lots of work…to say the least!
I’ve got an American linguistics book, which has a section on British English phonetics…but the examples are wrong and make no sense to a British English speaker 
I’ve seen nothing written about Oz vowels at all.
I think that’s a fairly good guide, other than some stuff on Wikipedia.
