My preference would be to use adaptive software either in conjunction with lap tops or iPads.
With laptops you can use Clicker 7 or 6, Penfriend Xp or voice to text software which is often integral to the machines accessibility settings ( but pretty useless) or a package like dragon naturally speaking.
Also useful is read/write gold, and Caro but I have never used these.
If you use iPads I’d use Clicker Docs or the integral voice to text and text to voice, which is very good.
