カナダ英語
Phonologically, Canadian and American English are classified together as North American English, emphasizing the fact that the vast majority of outsiders, even other native English speakers, cannot distinguish the typical accents of the two countries by sound alone. Canadians and Americans themselves sometimes have trouble differentiating their own two accents, particularly when the Canadian accent in question is Standard Canadian English: the mainstream mainland variety. There is even evidence that Standard Canadian English and some Western American English (Pacific Northwest and California English, for example) are undergoing a very similar vowel shift, since the 1980s. Most Canadian accents outside of Standard Canadian English fall under Atlantic Canadian English.
