I'm hoping 'this' is the right place, as my attempt on the Linguistic site failed miserably (it was moved to the ELL site, here -> Phonetic transcription of English prefixes and suffixes).
In case 'reasons' are required; I'm wanting to look at rhyme (true/near) and minimal pairs (true/near) (amongst other things) in both British and American English (I want to look at Canadian, South African and Australian later :D). Though I have a large list of words, I'm missing the pronunciation of many inflections. I thought I'd look at some dictionary entries, and noticed that many don't include transcriptions for inflected forms. Apparently (according to comments on Ling.) this is because the pronunciation is generally standard. I find this a little questionable - just looking at pluralisation shows three different pronunciations, and one of those creates an additional syllable.
I've found some general "rules of thumb" - but I'm left wondering how reliable/accurate they are.
I'm not expecting there to be rules without exception - but I'd like an idea if I'm looking at occasional exceptions, or lots of them.
* -s + [p] / [t] / [k] / [f] = 's' + [b] / [d] / [g] / [l] / [r] / [w] / [m] / [n] / [v] / [y] = 'z' + [tʃ] / [dʒ] / [s] / [z] = 'iz' (+additional syllable) *-ed + [p] / [k] / [θ] / [f] / [s] / [ʃ] / [tʃ] = 't' + [b] / [g] / [ð] / [v] / [z] / [ʒ] / [dʒ] / [m] / [n] / [ŋ] / [r] / [l] = 'd' + [t] / [d] = 'əd' or 'ɪd' (+additional syllable)
Are such rules fairly consistent?
Can I apply them with a fair degree of accuracy?
Are there established/known exceptions (or better, sub-rules for exceptions)?
Any idea on how to identify whether a past-tense verb should have ''əd' or 'ɪd'?
Are there such rules for Prefixes as well as Suffixes?
