Overview

3. Confidence-Based Confirmation
Overview
The system confirms based on how well it heard the User
This is a Usability enhancement to prevent frustration for errant utterances and unnecessarily slowing faster users
Some places where it conditionally confirms:
Cancelling from an submenu
Deleting a message
Hanging up
Some places where it always confirms:
Emptying your deleted items folder
Sending when “Hang-up” is uttered
Places where it never confirms:
Everywhere else (It would be too annoying)
