How do you change sensitivity of Atom Echos? - eviltoast

I have some Atom Echos installed as HA remote voice assistants. They’re very cool, but they seem to say “I’m sorry I didn’t understand that” a bit too often when I’m not addressing them.

The Echos are thinking I’m giving them commands when there’s a discussion between people in the room or when a show/movie/music is playing. I have a custom wakeword, but I don’t think any sounds happening in the background are sounding like it - there is only 1 word in English that rhymes with the first part of my wake word.

So I’m wondering if there’s a way to configure the Echos to be more strict on what they consider to be the wakeword, or to be less attentive to ambient sound (or to require a more direct command, like “WAKEWORD” said kind of loud).
