Yes, there used to be discussions in the users' list. 
Ogg is not designed for voice coding.  However, I am
not a programmer and I thought that 'low bitarte'
could be applied to voice coding as well.  Simply, I
did not know that they were technically so
incompatible.  O.K.  You can laugh at my ingnorance on
technological issues.

In one of the discussions, it was also said that voice
coding area was heavily patented.  Therefore, beside
the technical issue, it must be very difficult to
combine patent-free and voice coding.  Probably, there
is little can be done on this issue from Vorbis
project and this is not to be discussed here as you
remarked before.
