Is "in-TEST-eyen" /ɪnˈtestaɪn/ a valid pronunciation for "intestine"? I looked up "intestine" in MacMillan, Oxford, Cambridge, Merriam-Webster and even the Longman Pronunciation Dictionary, none of which recommends that pronunciation. However, I've heard at least two Canadians use it (Matthew Santoro and one of those guys on ASAP Science on YouTube). I have no access to any Canadian English dictionary.
So, is "in-TEST-eyen" /ɪnˈtestaɪn/ a valid (common and accepted as correct, not as a mispronunciation) pronunciation for "intestine"? Or is it just valid in Canada? Or did those Canadians simply mispronounce it?
