Exactly my same thought. At least in the context of Internet Audio Conference.
Even 3G AMR, I think that was pre 2000 Speech Codec started at 5Kbps. With a latency of only ~20ms. If I am reading correctly the encode due to ML nature would take at least 40ms on Lyra.
I am sure there are some specific usage that would be a great use case. But most consumer consumption I cant think of one on top of my head. One should also be aware of the current roadmap in 5G and the on going work in 6G. We still have a long way to go in maximising bandwidth / transfer per capita.
It seems to be the case ML codec wants to take these speech codec to new low bitrate. While it is fun doing it as a research, I much rather they push the envelop at least 6 / 8Kbps closer to perfection with even lower latency ( 10ms if not lower ).
