I gave up on Echo Speaks because my "speak needs" are limited. Echo can speak defined phrases with routines triggered by virtual contact sensors. I have the Show announce garage door openings/closings, mailbox opening and a couple of others. A clever one is an Amazon skill that allows an mp3 file to be played. I'm using the old AOL "You've got mail." for the mailbox.
