How to use Voice Assist on mobile app?

I tried to use Assist on my iOS HA app for the first time today. It works if I type a command into the box. But when I try to use voice it’s like it just doesn’t hear me. I verified that I granted access to the microphone. Am I doing something wrong?

OK, I guess I need to install Whisper and Piper in order for it to work?

But I’m running HA in container, so I cannot use HA add-ons. Can I run these directly in Docker?
