Speex and Opus bottom out around 6000-8000 bps. Codec2 starts at 3200 bps and goes down to 700 bps. The original target use for Codec2 is real-time transmission in the HF (shortwave) and VHF/UHF amateur radio bands where those are about as much as you can transmit within the same bandwidth as analog voice modes once you factor in error correction.
