You could look into using esp32's for it. There's variants with copper ethernet and people have used them before to both act as voice assistant mics and to play back audio with Home Assistant. Real time stream audio reproduction might be too much for them but it's worth a spelunk if anyone has already gotten close enough.

Are you looking for two way audio? Or just transmitter to receivers only?
