My solution - buy a high end smart phone - the more (directional) mics it has the better. Add a high quality "spouse mic" that you can place whereever you want on conference table/dining table/nightstand/next to the door bell. Most phones, home assitants, the kinect etc come with with mic arrays and have ridiculously sophisticated audio stacks. You can't do cutting edge speech rec without those stacks.

These ridiculous hearing aid companies are going to go the way of dinosaurs soon. And good riddance.
