I agree. I would give the middle syllable more of an 'o' sound as well, rather than the 'uh' sound from the link.After looking up myocyte at dictionary,com & hearing the Pronunciation given for the word I would never have recognised it!
Being a Brit I would have pronounced this as "My-o(h)-Site". I don't do phoentics, but I have tried reconstructing using info from dictionary.com
I would guess my pronunciation is maɪ oʊ saɪt (IPA pronounciation).
So rich7, which English pronunciation do you want? There are many more....
