blind-accessible Linux on cell phones

[Linux for blind general discussion]

Various versions of Linux are being ported to cell phones.  Although most of these projects hope to support a variety of phones in time, the PinePhone tends to be the initial target for many of them, as detailed here:

I'm particularly interested in:

- Manjaro (based on Arch Linux)
- Mobian (based on Debian)
- postmarketOS (based on Alpine Linux)

Is anyone else interested in the possibility of putting together a blind-accessible cell phone OS, based on one or more of these?  Of course, I'd love to hear about any existing work in this area!
