Русский
Russian text to speech.
Ten voices read Russian by its own rules: its numbers, its dates, its ordinals and its abbreviations — not another language's with a borrowed accent.
Ten birds, thirty-one languages.
All of them polyglot: the same voice reads Spanish, English or Japanese without changing timbre. And a text quoting another language switches on its own, paragraph by paragraph.
