Yes, I noticed on her Hannity interview she had appeared to have taken voice coaching......she’s not near as “nasally”.
She sounds great and her composure is excellent.
Palin has "grown up" as a candidate in the past 2 1/2 years; the voice is the biggest valid flaw she has left (to the extent that her voice is even relevant to her effectiveness), and she's working on it. That's pretty high praise indeed. She's not the only great potential candidate we have, but she is one of the best.
You’re right on the money. She is now speaking using her diaphragm. She is not speaking so excitedly which causes more air flow and that nasally speech. Although, I think some of that nasally sound is just a regional voice pattern.
