  I believe that the technical details of this appeared in IEEE transactions
  on Consumer Electronics. I think it was about the August or September issue.
  I've got a copy somewhere and could probably put up some of the highlights.
  The article was written by an engineer at Pioneer (where else).

  If I remember right, there were several modes available. The one described      here involved using the upper eleven teletext lines to contain compressed
  speech information. This would get about 2 seconds of information.

  The really interesting part was using it for downloadable program storage.
  They could also use up to two preceeding frames for data/speech storage
  and tie all the frames together with a common frame number. This got about 
  15-20 seconds of speech, but involved more complex controls circuitry.
