One way to find the Devuan support for accessibility related workflow is using the debtag system to see the accessibility related tags and then the related software in Devuan repos. Lets see an example:

$ debtags tagcat | grep "Tag.*accessibility"
Tag: accessibility::accessible-via:at-spi
Tag: accessibility::accessible-with:brltty-braille
Tag: accessibility::accessible-with:brltty-speech
Tag: accessibility::accessible-with:orca-braille

Tag: accessibility::accessible-with:speakup-speech
Tag: accessibility::accessible-with:yasr-speech
Tag: accessibility::input
Tag: accessibility::ocr
Tag: accessibility::screen-magnify
