    The concept of compiling the world's knowledge in a single location dates
    back to the ancient Library of Alexandria and Library of Pergamum, but the
    modern concept of a general-purpose, widely distributed, printed
    encyclopedia originated with Denis Diderot and the 18th-century French
    encyclopedists. The idea of using automated machinery beyond the printing
    press to build a more useful encyclopedia can be traced to Paul Otlet's 1934
    book Traité de Documentation. Otlet also founded the Mundaneum, an
    institution dedicated to indexing the world's knowledge, in 1910. This
    concept of a machine-assisted encyclopedia was further expanded in H. G.
    Wells' book of essays World Brain (1938) and Vannevar Bush's future vision
    of the microfilm-based Memex in his essay "As We May Think" (1945). Another
    milestone was Ted Nelson's hypertext design Project Xanadu, which began in
    1960. The use of volunteers was integral in making and maintaining
    Wikipedia. However, even without the internet, huge complex projects of
    similar nature had made use of volunteers. Specifically, the creation of the
    Oxford English Dictionary was conceived with the speech at the London
    Library, on Guy Fawkes Day, 5 November 1857, by Richard Chenevix Trench. It
    took about 70 years to complete. Dr. Trench envisioned a grand new
    dictionary of every word in the English language, and to be used
    democratically and freely. According to author Simon Winchester, "The
    undertaking of the scheme, he said, was beyond the ability of any one man.
    To peruse all of English literature – and to comb the London and New York
    newspapers and the most literate of the magazines and journals – must be
    instead 'the combined action of many.' It would be necessary to recruit a
    team – moreover

I am also experiencing this with ElevenLabs Multilingual V2 voices. I am able to use the Flash or Turbo models, but the quality is significantly reduced.
