If I'm not mistaken, elocution was once part of the curriculum in secondary schools ... but today, I gather that pupils make more presentations (than when I was in school), so perhaps things even out somewhat. I had a vocal instructor from Britain (Royal Court) who had us do a technique similar to what Mr. Frid demonstrated - so I'm sure voice is still taught in some acting schools. Some of the reporters (specifically, women) on CNN have the most irritating nasal way of speaking, evidently it's a trend. I keep wanting to tell them to drop their voices to a lower register. (I don't claim that my classes had a lasting effect on me, but then I'm not on TV.)
