Lowest bitrate speech codecs have rates like 450bps, 700bps (Codec2) and 1600bps (LPCNet) https://github.com/mozilla/LPCNet https://github.com/mozilla/LPCNet https://github.com/drowe67/codec2 https://github.com/drowe67/codec2 Conceivably one could reach 39 bps with near-realtime speech, tone, inflection and tempo recognition. Put the result into a zstd compressed SSML stream and perhaps even reach 16 bps. https://stackoverflow.com/questions/46108940/is-there-a-way-to-convert-speech-directly-into-ssml https://stackoverflow.com/questions/46108940/is-there-a-way-...
