IMHO, text to speech or speech to text used by disabled people should have "no" and "fuck" in the most minimal vocabulary option.
What do you do if a kid hits "fuck" over and over and over again and laughs? Probably the same thing you'd do to a non-disabled kid who says fuck over and over again.
The next most important thing on devices is privacy. Too many devices have logging modes that log communication without user consent. Disabled people (inc. kids) should have some privacy.
