Speaking without thinking must be something really important theses days. Andoid is even more built around touching (most of the android devices around have no keyboard at all !)

I second the suggestion of symbian. My e71 for example has a (built-in) application that actually speaks menus as you browse them. (at least the more important ones) also a no touchscreen qwerty device (or even number keypad with disabled t9) could proveto be much more useful - in that line you might want to check the e52, e72 and e5. I hope the app I'm talking about is still included with the newer symbians.
