Speex dev - Jun 2006 - codec at very low bit rate (2 kbps)

Hi to everyone.
I'm using speex in an application at the minimum bit rate (2.15 kbps),
setting the encoder quality at 0, but obviously the quality is terrible. My
question is: there are some signal processing that I can do to improve the
quality of the signal at very low bit rate? Or can you tell me other codec that
works well at that rate?
Thank you.

Do a search on "Voxware MetaVoice".  I'm not sure who licenses the
underlying technology these days (it's not Voxware anymore), but they do
have solutions that work in the 1200-2900 bps range.
