Web, No pronunciation scores, Free, ★
This valuable site has thousands of words recorded in six rare, nearly-extinct languages. Audio quality varies, and it is not clear which are native speakers. It does not have sentences or grammar, and you usually find and display one word at a time, not, for example, "colors" or "fruits," though "numbers" displays 12 of the numbers up to 20. The site is hosted at Swarthmore College.
