Have you seen or heard this comment about Trump's voice?

I’ve noticed this effect, but I haven’t seen any comments about it, and I wonder if anyone else has:

From the very first time I heard Donald Trump speak, his voice set my teeth on edge. It’s not the slightly raspy quality or the tenor pitch or the gospel-preacher cadences and intonations. It’s something I can only describe as false or phony-sounding because it never seems to touch bottom. I don’t know how else to put it. It sounds falsely lifted, artificially controlled in a deliberately ingratiating way, not dropping into its natural lower registers. It seems not to use the bottom 20% of its range.

Maybe there are technical terms for this effect, but I don’t know them.

Anyway, that’s why, when I heard his remarks from Trump Tower on Tuesday, I was so riveted. At one point his voice sharply changes. Hear it here in this excerpt. It’s just a few seconds in (less than 30):

When he says “Wait a minute, I’m not finished,” his voice suddenly becomes deeper, sharper. It loses its sanded-off character and grabs an edge. It sounds angry. And it sounds authentic.

I think that at that moment we are hearing his real voice. And I think everyone in his boardrooms will know that voice. Every employee will know that voice. His wives and his children will know it. But it’s not the practiced public voice we usually hear.

So I want to know if you have seen any newscaster or commentator or columnist talk about this. I’m curious to know if this is a shared perception.
