It has long been an assumption in the field of English as a foreign language that those who speak the language as natives pronounce the way it should be taught. Most influential figures in the field have been outsiders, and the subject has accordingly not been really defined as the teaching of English as a foreign language, but as the teaching of English to foreigners: quite a different thing. This book discusses the designing of programs for learning which will take the different kinds of foreign-ness into account.
