Transliteration keyboards for braille screen input

I still can't write anything basic in punjabi, not even read it in braille even if the code apparently exists. The voices now are an okayyy ish first step but for typing it's terrible, a lot of weird tts &&& ... arthefacts. I wonder sometimes why apple even bothered including such obviously incomplete product as shipping software but I can read bits now so it's better than nothing as espeak on ios is a terrible quality tts.
