It would make mor sense to me to have soetihng that does as Masayasu is
suggesting - if it can handle language changes to make them (and only
signpost them if asked) but if it cannot handle the language, then it should
say something like "Korean text - unable to read".

  Hmm ... if language change doesn't occur frequently, that would make
  sense, but when it occurs frequently, I think announcing language
  changes would be rather annoying than helpful.
  Suppose that a user's primary language is Japanese, and a speech user
  agent supports Japanese and English.  These days many English words
  appear in Japanese documents, especially in technical documents.
  For example, when I'm reading a guidebook for HTML, I don't want to
  hear "English Phrase" "HTML" "end English Phrase" each time a word
  "HTML" appears if a UA doesn't support configuration - in that case
  I have no way to stop it!  Anyway, I strongly recommend that UAs
  should allow configuration so that users can choose not to announce
  language changes.

  BTW, I'm wondering what a UA should do when most part of a document
  is written in unsupported language(s).  I tried IBM's Home Page
  Reader 2.5 (English version), and it does change speech engine
  when a document's language is specified via the `lang' attribute
  of the `html' element.  It speaks languages like French and German
  pretty well, in addition to English.
  However, when it encountered a Japanese document, which is not
  supported by the English version of HPR, the result was quite
  terrible.  It got all Japanese characters as garbage (i.e.
  misinterpreted them as Latin-1 characters), and just read those
  garbage literally.  Just too bad.
  (Note: the Japanese version of HPR speaks Japanese pretty well, though.)
  In this case, is it appropriate that just announcing the document's
  language is not supported and don't read the document?
