Alexa, Emulated Hue, Haaska, Skills - huh?

Alright so there is alot of ways to interact with alexa and ha, I am looking to understand a little better here. Ive used emulated hue for months and works great, no issues. Last night I discovered intents and i havent been to bed, ive turned my alexa into a complete ***hole lol. I love this, but I really hate the “hey alexa, ask big booty judy to …”

From what Ive read is hasska you dont have to say ask blah blah blah you can talk normal. But from what Ive also read it sounds like haaska is kinda an alternative to buying an alexa and runs on a pi with a mic? I dont need that piece I just want to be able to customize her responses without having to ask big booty judy.

Is that possible?

Thanks!
