Spoken Wikipedia aims to produce recordings of Wikipedia articles being read aloud.
"This page lists articles for which a spoken word version of the article has been created as part of the Spoken Wikipedia Project."
For example, "created from a revision of Politics and the English Language dated 2007-01-21, and does not reflect subsequent edits to the article."
["Politics and the English Language" (1946) is an essay by George Orwell criticizing "ugly and inaccurate" contemporary written English.] Wikipedia
