Pico TTS using Alexa Echo devices!

I have couple of echo devices laying around downstairs and upstairs !

Can I set them up as media players using Alexa Media player integration in HACS and still use pico TTS to make announcements on them ?

My intention was to use local processing for TTS and not depend on Amazon cloud for processing ! However the issue is I don’t have raspberry PI’s or hifi systems with speakers that I can set up as media players in home assistant !

Bumping this and hoping for a reply !
