I'm developing a new third party keyboard aimed at low vision users, for instance those that use large text or zoom accessibility features.
It is going to have both optional self-voicing for announcement of characters and words, as well as support for VoiceOver.
Hopefully it will also in time have spelling correction and other features to be shared with MBraille Keyboard.
I'm the author of MBraille, so there is a fair chance that this project will result in something usable and will not drag on for months without a release. :) There is also considerable synergy between the two projects, so no need to worry that MBraille development will stop.
If you would like participate in beta testing, send me mail at: harri at mpaja.com
All the best,
