My experience of voice recognition is that you need to be fairly clued up to
use it. (in fact rather determined really). People feel strange speaking
commands into a microphone - this might be worse for someone with dementia.
Also the error rate is more important. You need to know what to do when it
mis-recognises, in this case dialing the wrong person. I've also found that
with the Pilot, unless you send it to sleep , it will recognise the odd
extraneous noise. It is infuriating for the user to be watching Coronation
Street, the Pilot recognises someone shouting outside and turns over to
bbc2. The user then gets frustrated and their voice tone changes, making
recognition even worse. And if the user's voice tone changes when trying to
wake it up, then they're really stuck!
Having said all this, I ought to say that I still think voice recognition
is good for the right person. The user just needs to be clear about their
error correction strategies.
Does anyone have contradicting experience?
