I’ve wondered about adding a microphone to the inside and speaker to the outside. Such tech is pretty cheap these days, so it wouldn’t add much overhead to a reusable respirator.
The overhead is mainly the “fixed cost” of engineering something that works well, which suggest re-using some of the engineering costs already incurred in making it possible for a person to make a hands-free phone call on a smartphone.
