Hi.
Just to let you know that a self voicing version of MBraille is available on Windows:
https://apps.microsoft.com/detail/9pc8z5m4vnz1
That app is meant for learning braille and does have large font preview of the text your are typing. So if you are loosing your vision, but can still see large text, and want to learn braille, then MBraille on Windows can be a useful learning tool.
The Windows app is completely free, and does not contain any ads.
To learn more about MBraille and different versions, go to https://mpaja.com/mbraille
Best regards,
Harri
