[Blind-sysadmins] screen reader Accessibility with bitlocker

Hello: I would like to know is there a way to make bit locker accessible with a screen reader. Currently, we set up a passcode for our users and they have to type in that passcode in order to boot their computer. However, currently there is no screen reader accessibility during this process. Is there a way to make this process accessible? If not, what other solutions are out there for bit locker accessibility? Thanks in advance. Kathryn
