As a Local Guide, I see people struggling to type quickly while on the go. In Bangladesh and West Bengal, millions of users prefer ‘Banglish’ (speaking Bengali but writing in Roman/Latin script).
Currently, Gboard doesn’t support voice typing for this. If Google adds a ‘Bengali (Latin)’ voice-to-text option, it would significantly improve accessibility for millions of users who find manual typing difficult. Please consider this feature for the next Gboard update!
