Need Opinion ASAP

[Induction Concepts]

First, I don't know much about the particular voice control technology you're working with, but a couple of things come to mind.

I have used some of these things in the past and they required 'training'. If they still require this, and you only had voice control, what happens if you get strep throat or a bad cold, where your voice sounds different? On top of an already sore throat (and feeling like crap), it might take a lot of work 'vocally' to get things to work.

What about others that drive the vehicle (wife, dad, whatever), they would have to 'train' it also?

Then again, the technology may be light-years ahead now and not require this.

At least with a combination, you have a choice. Again, I know very little about it, just some thoughts that came to mind.
