Nope. They worked with piezo electric transducers. Not microphones. Entirely different tech.

No.

Think of the difference of hearing and listening.

If you hear someone talking but don't know what they're saying, you are just hearing, not listening.

When you understand what they're saying, then you're listening.

The handicapper doesn't know is constantly trying to detect ('hearing') for a certain noise, but doesn't know what any other noises are. Once it hears a certain noise, then it turns on/off.

This is essentially how all voice assistants work. They're 'hearing' for a specific sound to activate the part that then is actually listen.
