Special English
From Wikipedia’s entry on Special English… “Special English is a controlled version of the English language first used on October 19, 1959, and still presented daily by the United States broadcasting service Voice of America (VOA). World news and other programs are read one-third slower than regular VOA English. Reporters avoid idioms and use a core vocabulary of about 1500 words ,[1] plus any terms needed to explain a story. The intended audience is intermediate to advanced learners of English. Transcripts, MP3s, archives and podcasts of programs are provided at voaspecialenglish.com” Wikipedia also has all the words listed in their VOA: Special English Word Book.
