I'm not so sure. Have you watched them type on computers and phones? It's a bit more complicated because you need an IME, sure, but it doesn't seem to make that much of a difference. I guess it's tempting to draw that conclusion, but I think it's much more related to culture. Even among European countries, and within countries but between age groups, the usage of voice vs text is pretty different.
